How to solve your problem
−2(1−4)=3+8
-2(1-4x)=3x+8−2(1−4x)=3x+8
Solve
1)
Rearrange terms
−2(1−4)=3+8
-2({\color{#c92786}{1-4x}})=3x+8−2(1−4x)=3x+8
−2(−4+1)=3+8
-2({\color{#c92786}{-4x+1}})=3x+8−2(−4x+1)=3x+8
2)
Distribute
−2(−4+1)=3+8
{\color{#c92786}{-2(-4x+1)}}=3x+8−2(−4x+1)=3x+8
8−2=3+8
{\color{#c92786}{8x-2}}=3x+88x−2=3x+8
3)
Add
2
22
to both sides of the equation
8−2=3+8
8x-2=3x+88x−2=3x+8
8−2+2=3+8+2
8x-2+{\color{#c92786}{2}}=3x+8+{\color{#c92786}{2}}8x−2+2=3x+8+2
4)
Simplify
Add the numbers
Add the numbers
8=3+10
8x=3x+108x=3x+10
5)
Subtract
3
3x3x
from both sides of the equation
8=3+10
8x=3x+108x=3x+10
8−3=3+10−3
8x{\color{#c92786}{-3x}}=3x+10{\color{#c92786}{-3x}}8x−3x=3x+10−3x
6)
Simplify
Combine like terms
Combine like terms
5=10
5x=105x=10
7)
Divide both sides of the equation by the same term
5=10
5x=105x=10
55=105
\frac{5x}{{\color{#c92786}{5}}}=\frac{10}{{\color{#c92786}{5}}}55x=510
