The two what? This question needs more context
It takes him 1 hour to read 30 pages so he’ll be reading 15 pages in 30 minutes so
17 pages in 34 minutes
Y + 4x = 8
y = 8 - 4x
substitute 8 - 4x for y in the other equation.
5x + 2(8 - 4x) = 13
5x + 16 - 8x = 13
-3x = -3
x = 1
y = 8 - 4(1) = 4
215,000 x 5.2% =11,180 quarterly compounded interested
quarter = 4 theres 4 quarters in a year
3years x 4 quarters= 12 quarters
12 quarters x 5.2% of 215,000 =
134,160(compounded interested)+ 215,000(money he owes) =
349,160
