900=\left(4x+5\right)\times 2
Anything divided by one gives itself.
900=8x+10
Use the distributive property to multiply 4x+5 by 2.
8x+10=900
Swap sides so that all variable terms are on the left hand side.
8x=900-10
Subtract 10 from both sides.
8x=890
Subtract 10 from 900 to get 890.
x=\frac{890}{8}
Divide both sides by 8.
x=\frac{445}{4}
Reduce the fraction \frac{890}{8} to lowest terms by extracting and canceling out 2.
