Question

Resolva :
A- 4x-6=22
B- 9y=24
C- 13m+1-10m=5+m
D- 2 . (Z+3) - 5=z+5

Answer 1

A)
4x - 6 = 22
4x = 22 + 6
4x = 28
x = 28/4
x = 7

********************
B)
9y = 24
y = 24/9

****************************
C)
13m + 1 - 10m = 5 + m
3m + 1 = 5 + m
3m - m = 5 - 1
2m = 4
m = 4/2
m = 2

*****************************
D)
2.(z + 3) - 5 = z + 5
2z + 6 - 5 = z + 5
2z + 1 = z + 5
2z - z = 5 - 1
z = 4
