Question

a)4x+3=2x-5 b)2x+5=13-x
​

Answer 1

a) 4x + 3 = 2x -5

4x - 2x = -5 -3

2x = -8

x = -8/2

x = -4

b) 2x + 5 = 13 - x

2x + x = 13 - 5

3x = 8

x = 8/3

x = 2,66

Answer 2

Resposta:

a)x=(-4)

b)x=8/3

Explicação passo-a-passo:

a)4x+3=2x-5

4x-2x=(-3)-5

2x=-8

x=(-8)/2

x=-4

b)2x+5=13-x

2x+x=13-5

3x=8

x=8/3
