Question

x-17=-9

2x+2=2x-11

2x+2=2x-11

5x+4-2x=26-3x

10x-8-2=7x-4

3•(x+2)+5=x+12

5•(3x-2)=2•(6x+3)

2x/3+1/2=x/4-3/2

Answer 1

x-17 = -9
x = -8+17
x = 9

2x+2 = 2x-11
2x-2x = -11-2
0 = -13

5x+4-2x = 26-3x
5x-2x+3x = 26-4
6x = 22
x = 22/6

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

3•(x+2)+5 = x+12
3x+6+5 = x+12
3x-x = 12-6-5
2x = 1
x = 1/2

5•(3x-2) = 2•(6x+3)
15x-10 = 12x+6
15x-12x = 6+10
3x = 16
x = 16/3

A última vou fazer no papel e mandar foto
