4x+48=y

- algebra -
**Damon**, Friday, July 22, 2011 at 7:33pm8 x - 3 y = -88

8 x - 3 (4 x + 48) = -88

8 x - 12 x - 144 = -88

-4 x = 56

x = -14

then get y

**Damon**, Friday, July 22, 2011 at 7:51pmx 30 sec or .5 min

y 60 sec or 1 min

x + y = 14

.5 x + y = 11

---------------- subtract

.5 x + 0 y = 3

x = 6

y = 14-x = 8

----------------------------

----------------------------

check

6*.5 + 8 = 3+8 = 11
