x + y = 98
1 less than 8 times smaller is (1/8x) - 1. 8 times smaller means divided by 8. (4 is 8 times smaller than 32.)
x = 1/8y - 1
x + 1 = 1/8y
8(x+1)= 8(1/8y)
8x + 8 = y
Substituting, we get:
x + (8x + 8) = 98
9x + 8 = 98
9x = 90
x = 10
10 + y = 98
y = 88
And checking the answer, we get:
1 less than 8 times smaller
88/8 = 11
11 - 1 = 10
So the final answer is:
x = 10, y = 88

For # a million: y=x-3 x+y=21 x+(x-3)=21 2x-3=21 2x-3+3=21+3 2x=24 x=12; y=x-3 y=12-3 y=9 both numbers are 12 and 9. For #2: x=8y-a million x+y=ninety 8 8y-a million+y=ninety 8 8y+y=ninety 9 9y=ninety 9 y=11 x=8y-a million x=8*11-a million x=88-a million x=87 both numbers are 87 and 11.

87 is the greater number, 11 is the smaller
g=8s-1
g+s=98
8s-1+s=98
9s=99 s=11
g=8s-1=88-1=87

the larger of the two numbers is 87
x=8y-1
x+y=98
8y-1+y=98
9y=99
y=11
x+11=98 or 8(11)-1=98
x=87

98=x-(8x-1)
98=x-8x+2
96=7x
x=13.71
