0.5(x - 3) + (1.5 - x) = 5x
0.5x - 1.5 + 1.5 - x = 5x
-0.5x = 5x
5x + 0.5x = 0
5.5x = 0
x = 0
X represents nickels
y represents dimes
x+y=29
5x+10y=210
multiply the first equation by -5 (elimination method)
-5x-5y=-145
then add the two equations together
5y=65
divide 5 from both sides
y=13
13 dimes
Y = -3/8x - 7....add 3/8x from both sides
3/8x + y = -7 ...multiply both sides by 8
3x + 8y = - 56 <==
