4x+4-3\left(x-1\right)=2x+3\times 3.4x
Use the distributive property to multiply 4 by x+1.
4x+4-3x+3=2x+3\times 3.4x
Use the distributive property to multiply -3 by x-1.
x+4+3=2x+3\times 3.4x
Combine 4x and -3x to get x.
x+7=2x+3\times 3.4x
Add 4 and 3 to get 7.
x+7=2x+10.2x
Multiply 3 and 3.4 to get 10.2.
x+7=12.2x
Combine 2x and 10.2x to get 12.2x.
x+7-12.2x=0
Subtract 12.2x from both sides.
-11.2x+7=0
Combine x and -12.2x to get -11.2x.
-11.2x=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-7}{-11.2}
Divide both sides by -11.2.
x=\frac{-70}{-112}
Expand \frac{-7}{-11.2} by multiplying both numerator and the denominator by 10.
x=\frac{5}{8}
Reduce the fraction \frac{-70}{-112} to lowest terms by extracting and canceling out -14.
