x = 4
First, distribute the 3 into (2x - 5)
6x - 15 = 4x - 7
Next, to solve for x you want to isolate it onto one side. To do this subtract 4x from both sides
2x - 15 = -7
Add 15 to both sides so 2x is alone
2x = 8
Finally divide both sides by 2
x = 4
To double check this, plug in 4 to the original equation. If x=4 is the correct solution, both sides should equal each other.
3(2(4)-5)=4(4)-7
3(8-5)=16-7
3(3)=9
9=9
Both sides equal each other so x=4 is the correct solution
