e) X = 58-4
f) 4x - 6 =22
g) 9-X = 2x​

Answer 1

Resposta:

Olá!

Explicação passo-a-passo:

a. $2x+9=-62$

$2x=-62-9$

$2x=-71$

$x=-\frac{71}{2}$

b. $3x-16+5=41$

$3x=41+16-5$

$3x=52$

$x=\frac{52}{3}$

c. $6x-5x+12=42$

$6x-5x=42-12$

$x=30$

d. $-6+8x+2x=18$

$8x+2x=18+6$

$10x=24$

$x=\frac{24}{10}=\frac{12}{5}$

e. $x=58-4$

$x=54$

f. $4x-6=22$

$4x=22+6$

$4x=28$

$x=\frac{28}{4}$

$x=7$

g. $9-x=2x$

$9=2x+x$

$3x=9$

$x=\frac{9}{3}$

$x=3$

Bons Estudos!
