we get x by setting up a proportion.
=
then we cross multiply.
12(5x−1) = 21(2x+2)
60x − 12 = 42x + 42
18x − 12 = 42
18x = 54
<u>x = 3.</u>
plug in 3 for x for <u>LB</u>, which is <u>2x + 2.</u>
<u>LB </u>= 2(3) + 2 = 8
plug in 3 for x for <u>BG</u>, which is <u>5x - 1.</u>
<u>BG </u>= 5(3) - 1 = 14
