To expand, you just take the 5 and multiple by each individual factor.
10 x 5x + 5y x 10
{12x 4y = 15232x 12y = 42012x 4y = 15232x 12y = 420?In the equations, xx represents the cost of a chicken lunch and yy represents the cost of a v.... I think... "Xx represents the cost of a chicken lunch..."
cross multiply the equation to give you
1= a(2bh+3)
divide both sides by a(2b+3)
answer is 1/2ab+3 = h
