Question

Determine a raiz de cada equaçao

5x +18= -2+3×




3+7×(x-4)=-(3x-10)

Answer 1

Resposta:

Explicação passo-a-passo:

A) 5x + 18 = -2 + 3x

5x - 3x = -2 - 18

2x = -20

x = -20÷2

x = -10

B)3 + 7.(x - 4) = -(3x - 10)

3 + 7x - 28 = -3x - 10

7x + 3x = -10 - 3 + 28

10x = 15

X = 15/10

X = 3/2
