Black and white copies cost $0.05 each, and color copies cost $0.49 each. The equation 0.05x+ 0.49y=5 represents the number of b
lack and white copies x and color copies y that can be made with $5. If no color copies are made how many black and white copies can be made with $5
1 answer:

1/4a + 1/3a +8 =22
1st step add like terms:
1/4a +1/3a = 3/12a +4/12a = 7/12a
7/12a +8 =22
2nd step subtract 8 from each side:
7/12a = 14
3rd step divide both sides by 7/12 to get a:
a = 14 / 7/12
a = 24
14 = 31.7 - 3x
-17.7 = -3x <---- I subtracted 31.7 from both sides
5.9 = x <---- I divided both sides by -3
