Answer 1

Respuesta:

Problema #1⇩

$5(x - 2) = 2x + 5 \\ \\ 5x - 10 = 2x + 5 \\ \\ 5x - 2x = 5 + 10 \\ \\ 3x = 15 \\ \\ x = \frac{15}{3} \\ \\ x = 5$

Problema #2⇩

$2(x + 2) + 3(x + 1) = 47 \\ \\ 2x + 4 + 3x + 3 = 47 \\ \\ 5x + 7 = 47 \\ \\ 5x = 47 - 7 \\ \\ 5x = 40 \\ \\ x = \frac{40}{5} \\ \\ x = 8$

Problema #3⇩

$7(x - 1) = 3x + 5 \\ \\ 7x - 7 = 3x + 5 \\ \\ 7x - 3x = 5 + 7 \\ \\ 4x = 12 \\ \\ x = \frac{12}{4} \\ \\ x = 3$

Problema #4⇩

$6(x + 1) = 2(11 + x) \\ \\ 6x + 6 = 22 + 2x \\ \\ 6x - 2x = 22 - 6 \\ \\ 4x = 16 \\ \\ x = \frac{16}{4} \\ \\ x = 4$

Problema #5⇩

$5(x + 2) + 3x = 6x + 38 \\ \\ 5x + 10 + 3x = 6x + 38 \\ \\ 5x + 3x - 6x = 38 - 10 \\ \\ 8x -6x = 28 \\ \\ 2x = 28 \\ \\ x = \frac{28}{2} \\ \\ x = 14$

Espero sean de ayuda!✌
