to solve, we can solve for x in the 2nd equation and plug it into the first to find y.
subtract 3y from both sides
divide all parts by 2
plug this back into equation #1
distribute 15 to the quantity
change the fractions to a common denom of 2
drop the denoms
multiply
combine like terms
subtract 885 from both sides
divide by -23
pick either of the equations and plug y=27 in.
multiply
subtract 81 from both sides
divide both sides by 2
the solution, or ordered pair, where the two lines cross is :
(-11,27)
