Answer:
X = 8.3 (shortened)
Steps for answer!
1. Subtract 2.5x from both sides.
1.5=4x-11-2.5x
2. Simplify 4x-11-2.5 to 1.5x-11
1.5=1.5x-11
3. Add 11 to both sides.
1.5+11=1.5x
4. Simplify 1.5+11 to 12.5.
12.5=1.5x
5. Divide both sides by 1.5.
12.5/1.5=x
6. Simplify 12.5/1.5 to 8.3333338.333333.
8.333333=x
7. Switch sides.
x=8.333333
