Answer:
x =21/5 or 4.2
Step-by-step explanation:
Solve for x:
5x + 7 - x - 2 = 6x + 3x - 16
Combine the like terms in LHS and in RHS.
5x - x + 7 - 2 = 6x + 3x - 16
4x + 5 = 9x - 16
Add 16 to both sides.
4x + 5 + 16 = 9x
4x + 21 = 9x
Subtract 4x from both sides.
21 = 9x - 4x
21 = 5x
Divide both sides by 5.
21/5 = x
x = 21/5 or 4.2
