Question

1)Resolva equação.

a) 5X-40=2-X

b) 20+6x=-2x+28

c) 13y-5=11+9y

Answer 1

a) 5x - 40 = 2 - x
5x + x = 2 + 40
6x = 42
x = 42/6
x = 7
b) 20 + 6x = -2x = 28
6x + 2x = 28 - 20
8x = 8
x= 8/8
x= 1
c) 13y - 5 = 11 + 9y
13y - 9y = 11 + 5
4y = 16
y= 16/4
y = 4

Answer 2

A) 5x-40= 2-x
5x+x= 2+40
X= 42/6
X=7

B) 20+6x=2x+28
6x-2x= 28-20
X= 8/4
X=2

C) 13y-5= 11+9y
13y-9y= 11+5
Y= 16/4
Y= 4
