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

-2x+5x = 6-3

3x= 2

x= 2/3

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
