Answer:
c= ℝ
Step-by-step explanation:
8(c-9)=6(2c-12)-4c
Distribute left side.
8*c+8*-9=6(2c-12)-4c
8c-72=6(2c-12)-4c
Distribte right side.
8c-72=6*2c+6*-12-4c
8c-72=12c-72-4c
Combine like terms.
8c-72=8c-72
Since the two sides are exactly the same, this means that any number for c will satisfy the equation.
Therefore, c= ℝ (all real numbers)
