Question

1- calcule o valor de x:

a) X+2X=15 b) 3X-X=15
x
x
x

c) 5X=30 d) X:4=32
x
x
x

Answer 1

a) x+2x= 15
3x= 15
$x= \frac{15}{3}$

x= 5
b) 3x-x= 15
2x= 15
$x= \frac{15}{2}$

x= 7,5
c) 5x= 30
$x= \frac{30}{5}$

x= 6
d) x÷ 4= 32
x= 32.4
x= 128
Bons Estudos...

Answer 2

A) x + 2x = 15

3x = 15

x= 15/3

x= 5

B) 3x - x = 15

2x = 15

x= 15/2

C) 5x = 30

x= 30/5

x= 6

D) x/4 = 32

x= 32 • 4

x= 128
