Question

X+4=15
4x+12=0
5x-6=2x-3
4x=28
6(x-2)=12
X+3x=-1200.

Answer 1

Explicação passo-a-passo:

X+4=15

x=15-4

x=11

4x+12=0

4x=12

x=12/4

x=3

5x-6=2x-3

5x-2x=-3+6

3x=3

x=3/3

x=1

4x=28

x=28/4

x=7

6(x-2)=12

6x-12=12

6x=12+12

6x=24

x=24/6

x= 4

X+3x=-1200

4x=-1200

x=-1200/4

x=-300
