Answer: 9cm
Step-by-step explanation:
![7x10=70cmx^{2}](https://tex.z-dn.net/?f=7x10%3D70cmx%5E%7B2%7D)
4(x)=4x
1.) 70+4x=106 (subtract 70 on both sides)
2.)4x=36 (divide 4 on both sides)
3.)x=9
Answer:
![x = 16](https://tex.z-dn.net/?f=x%20%3D%2016)
Step-by-step explanation:
5x-12=3x+20
plus 12 both sides
5x=3x+32
-3x both sides
2x=32
divide by 2 both sides
x=16
