Answer:
x = 7
Step-by-step explanation:
Given
- 3(x - 1) + 8(x - 3) = 6x + 7 - 5x ← distribute parenthesis on left side and simplify
- 3x + 3 + 8x - 24 = x + 7
5x - 21 = x + 7 ( subtract x from both sides )
4x - 21 = 7 ( add 21 to both sides )
4x = 28 ( divide both sides by 4 )
x = 7
Answer:
x=7
Step-by-step explanation:
−3(x−1)+8(x−3)=6x+7−5x
(−3)(x)+(−3)(−1)+(8)(x)+(8)(−3)=6x+7+−5x(Distribute)
−3x+3+8x+−24=6x+7+−5x
(−3x+8x)+(3+−24)=(6x+−5x)+(7)(Combine Like Terms)
5x+−21=x+7
5x−21=x+7
Step 2: Subtract x from both sides.
5x−21−x=x+7−x
4x−21=7
Step 3: Add 21 to both sides.
4x−21+21=7+21
4x=28
Step 4: Divide both sides by 4.
4x/4=28/4
