Question

6. Sendo U = Z, RESOLVA a equação 4x -10( x + 1) – 2( x – 2 ) = 0

(A) V = { }
(B) V ={ -3/4}
(C) V = 0
(D) V = { 7/4}

Answer 1

Resposta:

Explicação passo-a-passo:

4x -10( x + 1) – 2( x – 2 ) = 0

4x - 10x -10 -2x +2 = 0

4x - 10x -2x = -2 -10

-8x = -12

x = $\frac{-12}{-8} = \frac{6}{4} = \frac{3}{2}$
