Question

Holaaa me podrían ayudar en esto

Answer 1

Explicación paso a paso:

1.

$2x + 7 = 11 \\ 2x = 11 - 7 \\ 2x = 4 \\ x = \frac{4}{2} \\ x = 2$

2.

$2x + 7 = 22 \\ 2x = 22 - 7 \\ 2x = 15 \\ x = \frac{15}{2}$

3.

$3x - 2 = 18 \\ 3x = 18 + 2 \\ 3x = 20 \\ x = \frac{20}{3}$

4.

$\frac{x}{2} - 5 = 20 \\ x - 10 = 40 \\ x = 40 + 10 \\ x = 50$
