Answer:
x = 0
Explanation:
To solve, simplify, then isolate "x" (bring all "x" to the left).
x = 4 + (4x - 4) Remove brackets
x = 4 + 4x - 4 Collect like terms
x = 4 - 4 + 4x 4 - 4 = 0, or nothing
x = 4x Bring "x" to the left
x - 4x = 4x - 4x Subtract 4x on both sides
-3x = 0 Get rid of multiplying by "-3".
Divide both sides by -3
x = 0
Check the answer:
Substitute x = 0 into the original equation. Remember to follow BEDMAS order.
x = 4 + (4x - 4)
0 = 4 + (4*0 - 4) Solve multiplication in brackets first
0 = 4 + (0 - 4) Subtract inside brackets
0 = 4 + (-4) Adding a negative is the same as subtracting
0 = 4 - 4 Subtract
0 = 0 Same answer
LS = RS Left side equals right side
This solution is correct.
