Question

1/5(50x+20)-(2x+4)=

Answer 1

12

Explanation:

following pemdas (parentheses, exponites, multiply, divide, add, subtract)

starting inside the parentheses

50x20=100

2x4=8

next divide

1/5= 0.2

since there is no sign inbetween 1/5 and (50x20) you multiply the answers

0.2x100=20

finally subtraction 20-8=12

Answer 2

10x+4-2x+4
= 8x+8


If you want the x
8x=-8
X=-1
