Question

Resolva a equação 2(5x+2) = 50.

x = 2

x = -2

x = 0

x = 1

x = -1

Answer 1

10x+4=50
10x=50-4
x=46/10
x=4,6

10x+4=2
4-2=10x
2=10x
x= 2/10
x=0,2

10x+4=-2
4+2=10x
10x=6
x=6/10
x=0,6

10x+4=0
10x=4-0
10x=4
x=4/10
x=0,4

10x+4=1
4-1=10x
10x=3
x=3/10
x=0,3

10x+4=-1
4+1=10x
10x=5
x=5/10
x=0,5
