Question

calcule 9×-3-4×=8×-7+×

Answer 1

Boa Tarde

$9x - 3 - 4x = 8x - 7 + x$

$5x - 3 = 9x - 7$

$5x - 9x = - 7 + 3$

$- 4x = - 4$

R: $x = 1$

Espero ter ajudado e bons estudos :)

Answer 2

9x - 3 - 4x = 8x - 7 + x

9x - 4x - 3 = 8x + x - 7

5x - 3 = 9x - 7

5x - 9x = - 7 + 3

- 4x = - 4 (-1)

4x = 4

x = 4/4

x =1

Resposta :x = 1
