Question

1. (3x - 2) + (5x – 4) = 100
El valor de x

Answer 1

x= 13.25

Explanation:

If you simplify that it becomes 8x-6= 100

Then, if you rearrange it, its 8x= 100+6 or 8x=106

So that means x= 13.25

Answer 2

3x-2+5x-4=100
(3x+5x)+(-2+-4)=100
8x+-6=100
8x-6=100
8x-6+6=100+6
8x=106
8x/8=106/8
X=53/4
