-10x + 8
x + 8 = -3
x = -11
x = 3
-7x = 15 - 2x
x = -3
How do you find the perimeter of a shape
add up all the sides
-3(6x - 5)
-18x + 15
x/-4 = -7
x = 28
4(x - 3) = 20
x = 8
5x - 3 = 2x + 6
x = 3
3x + 1 = 3x + 1
IMS (infinitely many solutions-any value of x will make the equation true)
-3x + 5 + 8x - 7
5x - 2
-x = 18
x = -18
-2(x + 6) = 36
x = -24
5x + 9 = 16 - 2x
x = 1
7x - 4 = 7x - 9
NS (no solution-no value of x will make the equation true)
-2b + 9 - 6b - 4
-8b + 5
1/2x = 6
x = 12
-14x + 8 + 6x = -24
x = 4
-5x - 1 = -4x + 5
x = -6
