Question

q)5.(2x + 3) = 24 +
r) 2.17x+ 2) + 12 = x+30
s) -3-152-25
t)6x-15 = 9​

Answer 1

Resposta:

q) 10x +15 =24

10x = 24-15

10x= 9

x= 9/10

r) 34x +4 +12 = x +30

34x -x +16=30

33x = 30 -16

33x = 14

x= 14/33

s) falta o x

t) 6x= 9 +15

x= 24/6= 4

Explicação passo-a-passo:

Answer 2

q.

5 × (2x + 3) = 24

10x + 15 = 24

10x = 24 - 15

10x = 9

x = 9 ÷ 10

x = 0,9

r.

2 × (17x + 2) + 12 = x + 30

34x + 4 + 12 = x + 30

34x + 16 = x + 30

34x + x = 30 - 16

35x = 14

x = 14 ÷ 35

x = 0,4

s.

- 3 - 152 - 25

- 180

t.

6x - 15 = 9

6x = 9 + 15

6x = 24

x = 24 ÷ 6

x = 4
