Each small kite costs $4, while each large kite costs $7. If the total money collected selling kites is $150, and 30 kites are s
old, which system of equations can be used to find out how many of each size kite are sold? Let s be the small kites and l be the number of large kites.
<span>Solve the following system of equations by linear combination:
3x + 2y = 7
y = x – 4
</span><span>3x+2(x-4)=7 now solve for x
3x+2x-8=7
combine terms
5x-8=7
add 8
5x=15
divide by 5
x=3
plug that into the second equation
y=3-4
y=-1
solution
