Question

Resolva dando o conjunto solução:
2x-3=14
4x=30-18
5x=x+14
x+4=20
6x=2x+16
2x-5=x+1
2x+3=x+4

Answer 1

2x - 3 = 14
2x = 14 + 3
2x = 17
x = 17/2
S = {17/2}

4x = 30 - 18
4x = 12
x = 12/4
x = 3
S= {3}

5x = x + 14
5x - x = 14
4x = 14
x = 14/4 dividindo por 2
x = 7/2
S = {7/2}

x + 4 = 20
x = 20 - 4
x = 16
S = {16}

6x = 2x + 16
6x - 2x = 16
4x = 16
x = 16/4
x = 4
S = {4}

2X - 5 = x + 1
2x - x = 1 + 5

x = 6
s = {6}

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