Question

Encontre as soluções das equações:
a)2X+1=3-4X+16
b)6x-40=2-X
c)6(4-X)-55=-5(2X+3)
​

Answer 1

a)

2x + 1= 3 - 4x + 16

2x + 4x= 3 + 16 - 1

6x= 18

x= 18/ 6

x= 3

b)

6x - 40= 2 - x

6x + x= 2 + 40

7x= 42

x= 42/ 7

x= 6

c)

6(4 - x) - 55= - 5(2x + 3)

24 - 6x - 55= - 10x - 15

- 6x + 10x= - 15 - 24 + 55

4x= 16

x= 16/ 4

x= 4

Answer 2

A)2x+4x=3+16-1
6x=18
X=18/6
X=3

B)6x+x=2+40
7x=42
x=42/7
X=6

C)24-6x-55=-10x-15
-6x+10x=-15-24+55
4x=-39+55
4x=16
X=16/4
X=4
