Answer:
the first question is x=68/3 in standard from it is 3x=68
the second question is x= - 11/10
Step-by-step explanation:
for the second question the negative is beside the fraction.
X - quarters, x+5 - dimes.
$74=7400 cents
Then
(25x+10(x+5))=(25x+10x+50)=(35x+50) cents.
35x+50=7400
35x=7400-50
35x=7350
x=7350/35
x=210 quarters
x+5=210+5=215 dimes
210 quarters and 215 dimes
