Get the x variable on one side and the numbers another side.
9/10(x + 2/3) = 4 1/2
Distribute the 9/10 across the x and 2/3.
(9/10)x + 18/30 = 4 1/2
Simplify 18/30 to make our life easier.
(9/10)x + 3/5 = 4 1/2
Subtract 3/5 from each side of the equation.
(9/10)x = 3 9/10
Divide both sides by 9/10.
x = 4 1/3
25=d+q
4.30= .1d + .25q
25=d+q
-17.20=-.4d+-q
7.80= .6d
d=13...... 13 DIMES
25= 13+q
12=q....... 12 QUARTERS
