Question

1/3 (2x - 1) = 7 algebra question

Answer 1

Multiplying both sides by 3
2x-1=3(7)
2x-1=21
Adding 1 on both sides
2x-1+1=21+1
2x=22
Dividing both sides by 2
2x/2=22/2
x=11

Answer 2

By distributive property we get
1/3(2x)-1/3=7
Multiplying both sides by 3
3/3(2x)-3/3=3(7)
2x-1=21
2x-1+1=21+1
2x+0=22
2x/2=22/11
x=11
Thus the value of x is 11
