Question

me ajudem urgente

a) x-18=-6
b) y+9=15
c)4x+6=9
d)5y+10=-8

Answer 1

a) x-18=-6

x = - 6 + 18

x = 12

b) y+9=15

y = 15 - 9

y = 6

c)4x+6=9

4x = 9 - 6

4x = 3

x = 3/4 ou x = 0,75

d)5y+10=-8

5y = - 8 - 10

5y = - 18

y = - 18/5 ou y = - 3,6

Answer 2

Resposta:

(a) x = 12

(b) y = 6

(c) x = 3/4

(d) y = -18/5

Explicação passo-a-passo:

(a)

x-18 = -6

x = -6+18

x = 12

(b)

y+9 = 15

y = 15 - 9

y = 6

(c)

4x+6 = 9

4x = 9 - 6

4x = 3

x = 3/4

(d)

5y+10 = -8

5y = -8-10

5y = -18

y = -18/5
