34 = 2x +8x + 8(3)
34 = 2x + 8x + 24
34 = 10x + 24
10 = 10x
<em><u>x = 1</u></em>

Step-by-step explanation:
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
