Each year, the interest is 60 000 x 6/100 = 3,600
in 8 years the amount of interests is 8 x 3600 = 28,800
he'll pay $88,800
4x+y=26 replace y with (x-4) & solve for x in this equation.
4x+(x-4)=26
4x+x=26+4
5x=30
x=30/5 <span>
x=6 answer.
y=6-4
y=2 answer.
Proof.
4*6+2=26
24=2=26
</span>26=26 <span>Y=x-4

4 + 9 = 13, the one carries over, so 3 + 1 + 1 = 5
