y + 3x = 5
To find y when x = -1 , replace " x " in our equation with " -1 " and solve for y .
y + 3(-1) = 5 Multiply 3 and -1 to get -3 .
y - 3 = 5 Add 3 to both sides of this equation.
y = 5 + 3
y = 8
So...... when x = -1 , y = 8 .
To find y when x = 0 , replace " x " in our equation with " 0 " and solve for y .
y + 3(0) = 5
y + 0 = 5
y = 5
So...... when x = 0 , y = 5 .
To find y when x = 2 , replace " x " in our equation with " 2 " and solve for y .
