Question

a) x/4=-3
b) 2x=15
c) 2x/3=-10

Answer 1

a) $\frac{x}{4} = -3$

$\frac{x = -12 }{4}$ (corta o 4)

x= -12

b) 2x = 15
x= $\frac{15}{2}$

x= 7,5

c) $\frac{2x= -10}{3}$

$\frac{2x= -30}{3}$ (corta o 3)

2x = -30
x= $\frac{-30}{2}$

x= - 15

Bons estudos!

Answer 2

a) x/4=-3

x= - 3 • 4

x= - 12

b) 2x=15

x= 15/2

c) 2x/3=-10

2x = - 10 • 3

2x= - 30

x= - 30/2

x= - 15
