Let x = smaller
x+20 = larger
"Four times the larger is 70 more than 5 times the smaller. Find the numbers."
4(x+20) = 5*x + 70
4x+80 = 5x + 70
Subtract 4x from each side:
80=x+70
Subtract 70 from each side:
10=x
x=10 Smaller
x+20 = Larger
10+20= 30 Larger
Check:
"Four times the larger is 70 more than 5 times the smaller. Find the numbers."
4*30 = 5*10 + 70
120=50+70
It checks.
