I really suck at math...
Solve each Inequality:
-4(3x-5)>-28
A.x<4
B.x<-1/4
C.x>4
D.x>-1/4
And could you explain how you did it so I finish my homework? Thanks.
+23254 -4(3x - 5) > -28
Use the distributive law on the left side:
(-4)(3x) - (-4)(5) > -28
-12x + 20 > -28
Subtract 20 from both sides:
-12x > -48
Divide both sides by -12:
(When you multiply or divide both sides of an inequality by a negative number, you must change the direction of the inequality; you don't change the direction if you are adding or subtracting or if you are multiplying or dividing by a positive number.)
x < 4
