Question 188107
let x and y be the number of pounds of blue grass and fescue respectively
:
x+y=50......eq 1
3.50x+1.7y=2.96(50)...eq 2
:
rewrite eq 1 to x=50-y and x's value of 50-y into eq 2 for all occurrences of x
:
3.5(50-y)+1.7y=148
:
175-3.5y+1.7y=148
:
-1.8y=-27
:
y=15 pounds
:
x=50-y=50-15=35 pounds
