Let shirts be x and ties be y 3x+5y=$60 Equation 1 (Equation 1 will be denoted by *) 2x+3y=$39 Equation 2 (Equation 2 will be denoted by !) *x2 6x + 10y = $120 !x3 6x + 9y = $117 *-! y = 120-117 =3
Ties are $3 each Substitute this value back into one of the original 2 equations: 3x+5y=$60 3x+(5x3) = 60 3x+15=60 3x=45 x=15
