Question

a) 10x - 3x = 16
b) 7x + 2x-2x = 40​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 10x - 3x = 16

7x = 16

x = 16/7 ≈ 2,2

b) 7x + 2x - 2x = 40

7x = 40

x = 40/7 ≈ 5,7

Answer 2

Resposta:

$A) 10x-3x=16$

$7x=16$

$\frac{7x}{7} =\frac{16}{7}$

$x=\frac{16}{7}$

$B) 7x+2x-2x=40$

$7x-2x=40+2x$

$6x=42$

$x=42/6$

$x=7$
