Answer:
x = 9
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
- [tex]7x - 4x = 4x + 27 - 4x[/tex]
- [tex]3x = 27[/tex]
Step 2: Divide both sides by 3.
- [tex]\frac{3x}{3} =\frac{27}{3}[/tex]
- [tex]x = 9[/tex]
Step 3: Check if solution is correct.
- [tex]7(9) = 4(9) + 27[/tex]
- [tex]63 = 36 + 27[/tex]
- [tex]63 = 63[/tex]
Therefore, x = 9.
