3/2
Isolate the variable by dividing each side by factors that don't contain the variable.
3x - 10x = 14
-7x = 14
x = -2
For this problem, I believe you would just have to plug in for x.
For example, -17 divided by 10 and so on.
The answer should be C, -70. -70 divided by 10 equals -7.
Perimeter of rectangle:2(length+width):2(13+7)=40
Perimeter of square:4(length of one side):4(x)=40
X=10
