Question

resolver em z as equações :
x+3=-5
2x-3=7
-x+2=2x-4

Answer 1

x+3=-5 / x=-5-3 / x=-8
2x-3=7 / 2x=7+3 / 2x=10 / x=10/2 / x=5
-x+2=2x-4 / x-2=-2x+4 / x+2x=4+2 / 3x=6 / x=6/3 / x=2

Answer 2

x + 3 = -5
x= -3 -5
x= - 8

2x- 3 = 7
2x= 3+7
2x= 10
x= 10/2
x= 5

-x+ 2 = 2x -4
-x  -2x = -2 -4
3x= 6
x= 6/3
x= 2
