1. substitute y with 2x-6 so the equation is 2(2x-6)-x=3. distribute 4x-12-x=3. combined like terms 3x-12=3. move the -12 to the other side 3x=15. divide x=5. plug x into any equation y=2(5)-6. distribute y=10-6. solve y=4 answer is (5,4)

2.   (-x+y=4)

    +(-2-y=2)

         -3x=6

divide x=-2. plug x into any equation -(-2)+y=4. distribute 2+y=4. move 2 over and solve y=2 answer is (-2,2)

3. (x-2y=2)*2----->      (2x-4y=4)

 (3x+4y=3)*1----->    +(3x+4y=3)

                                         5x=7

Divide x=7/5=1 2/5=1.4. plug x into anyequation 3(1.4)+4y=3. distribute 4.2+4y=3. move 4.2 over 4y=-1.2 solve y=-0.3

2/3m-2/3m=-2/3-1/3       0m=-1                   there is no soulution 

you need a calculaor for this but the foumula is a^2 + B^2=c^2 so for instance if one leg is 3 and another is 4 then 3^2+4^2=c^2  9+16=c^2            c^2=25 the square root of 25 is 5 so the hypotnuse is 5 for this equation

the way i think about it is how do i get from 100% to 80% well divide by 5 to get 20% and multiply by 4 to 80% so 32.76/5=6.55 then 6.55*4=26.2 so 80% of 32.76 is 26.2

first find the rate they are going from the first problem 324/4.5=72 so 72 miles per hour next subtract 576-324=252 now divided 252/72= it will take them 3.5 hours to reach there destination.

answer is 3.5 hours if you are including both days then the answer will be 3.5+4.5=8 hours

so the equation is                   3  7/10h=m               m is miles traveled h is how many hours  so         3 7/10 * 2 1/2=m the

37/10*5/2 = 185/20= 9.25 miles

solution to your problem is  9 1/4 miles

using distributive property 25*3=75     25*n=25n simplify 75/25=3 25/25=1 so the answer is 3/n so the answer to this so called hard question is really in the question the answer is 3/n

ok hold on 

the answer is....

94 remainder of 15

ok so plug in the variables (4*6^2)+(7^2) now do order of operation do the parentheses first so lets make it (4*36)+(49) simplify it even more 144+49 now solve 193 is your answer

so let 3,680=y and you have to solve 3,680=360x+1000. first subtract the 1000 from both sides the equation is now  2,680=360x next divide 360 to both sides x would equal 7.444444......since he only has 3,680 to spend if it is a decimal you need to round down so the total amount of months he can lease the car is 7 months
