Answer:
x=4
Step-by-step explanation:
Add like terms;
2x+5+3x-7=18
↓
5x-2=18
We want x by itself so we need to remove that negative 2, So add it on one side and to the other.
You should get this;
5x=20
now we divide by 5 (remember to do both sides) to get the x by itself,
and so you get x =4
I hope this helped!
