Question

4×+8=2×+14?
7(×+2)=5(×-3)?
​

Answer 1

4x + 8= 2x + 14

4x - 2x= 14 - 8

2x= 6

x= 6/2

x= 3

______________________

7(x + 2)= 5(x - 3)

7x + 14= 5x - 15

7x - 5x= - 15 - 14

2x= - 29

x= - 29/2

x= - 14,5

Answer 2

Resposta:

x=3

x=-29/2

Explicação passo-a-passo:

1-

4x-2x=14-8

2x=6

x=6/2

x=3

2-

7x+14=5x-15

7x-5x=-15-14

2x=-29
