4x+48=y

• algebra -

8 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

• algebra -

x 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
