5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
Answers :
x = 9
y = 7
Fritz is correct, in that the ratio is 1:2
Think of the ratio as a division
10:20 = 10/20
When you divide 10 with 20, you will get a decimal (or simplified fraction)
10/20 = 0.5
0.5 = 50 percent, or 1:2
Fritz is correct, in that 1:2 is the ratio
hope this helps
