Question

ALGUEM ME AJUDA PFVR É PRA HOJE!!!!!​

Answer 1

a) y - 426 = 700

y = 700 + 426

y = 1126

b) a/6 = 132

a = 132 . 6

a = 792

c) 6x - 19 = 71

6x = 71 + 19

6x = 90

x = 90/6

x = 15

d) 2x/5 + 4 = 10

2x/5 = 10 - 4

2x/5 = 6

2x = 6 . 5

2x = 30

x = 30/2

x = 15

e) x/3 + 4x = 39

x + 4x / 3 = 39

x + 12x / 3 = 39

13x = 39 . 3

13x = 117

x = 17/3

x = 9

f) x + x/2 = 12

2x + x / 2 = 12

3x / 2 = 12

3x = 12 . 2

3x = 24

x = 24/3

x = 8

g) x/4 - 1 = 2 + x/10

x - 1 / 4 = 2 + x/10

(x - 1) . 10 = (2 + x) . 4

10x - 10 = 8 + 4x

10x - 4x = 8 + 10

6x = 18

x = 18/6

x = 3
