Answer:
All real numbers are solutions.
2(3x+9)=9x+7−3x+11
Step 1: Simplify both sides of the equation.
2(3x+9)=9x+7−3x+11
(2)(3x)+(2)(9)=9x+7+−3x+11(Distribute)
6x+18=9x+7+−3x+11
6x+18=(9x+−3x)+(7+11)(Combine Like Terms)
6x+18=6x+18
6x+18=6x+18
Step 2: Subtract 6x from both sides.
6x+18−6x=6x+18−6x
18=18
Step 3: Subtract 18 from both sides.
18−18=18−18
0=0
