Question

resolva as equaçoes a baixo
2Y+3=11
2c-5=9
5z+5=25
10x-9=51
2a+2=18

Answer 1

a) y = 4

b) c = 7

c) z = 4

d) x = 6

e) a = 8

Answer 2

Resposta:

OLÁ

A)

$2y + 3 = 11 \\ 2y = 11 - 3 \\ 2y = 8 \\ y = \frac{8}{2} \\ \\ \red{y = 4}$

B)

$2c - 5 = 9 \\ 2c = 9 + 5 \\ 2c = 14 \\ c = \frac{14}{2} \\ \\ \red{c = 7}$

C)

$5z + 5 = 25 \\ 5z = 25 - 5 \\ 5z = 20 \\ z = \frac{20}{5} \\ \\ \red{z = 4}$

D)

$10x - 9 = 51 \\ 10x = 51 + 9 \\ 10x = 60 \\ x = \frac{60}{10} \\ \\ \red{x = 6}$

E)

$2a + 2 = 18 \\ 2a = 18 - 2 \\ 2a = 16 \\ a = \frac{16}{2} \\ \\ \red{a = 8}$
