9/4 = (2x+1)/(x+2)
A proportion is an equation of the form:
"FRACTION = FRACTION"
9 2x+1
——— = ——————
4 x+2
A proportion is solved by cross multiplying:
LEFT NUMERATOR times RIGHT DENOMINATOR equals
LEFT DENOMINATOR times RIGHT NUMERATOR
9 times (x+2) equals 4 times (2x+1)
9(x+2) = 4(2x+1)
9x + 18 = 8x + 4
x = -14
