Question

2) Relacione a 2a coluna de acordo com a 1a: ( ) -9
(A) 3x – 5 = 10 ( ) 11/5
(B) 2y = -18 ( ) 10
(C)4x + 4 = 12 ( ) 5
(D)7x – 50 = 2x ( ) 2
(E) 5y – 6 = 5

Answer 1

Resposta:

Olá!

Explicação passo-a-passo:

a. $3x-5=10$

$3x=10+5$

$3x=15$

$x=\frac{15}{3}=5$

b. $2y=-18$

$y=-\frac{18}{2}=-9$

c. $4x+4=12$

$4x=12-4$

$4x=8$

$x=\frac{8}{4}=2$

d. $7x-50=2x$

$7x-2x=50$

$5x=50$

$x=\frac{50}{5}=10$

e. $5y-6=5$

$5y=5+6$

$5y=11$

$y=\frac{11}{5}$

$A=5,B=-9,C=2,D=10, E=\frac{11}{5}$

Bons Estudos!
