X=cost for 1 soft taco
x=cost for 1 doubledecker
dory is
11.25=3x+3y
nemo buys
10=4x+2y
we have
11.25=3x+3y and
10=4x+2y
divide second equation by 2
5=2x+y
multiply by -3
-15=-6x-3y
add to first equatin
-15=-6x-3y
11.25=3x+3y+
-3.75=-3x+0y
-3.75=-3x
divide both sides by -3
1.25=x
subsitute
5=2x+y
5=2(1.25)+y
5=2.5+y
minus 2.5
2.5=y
double dekesr cost $2.50
soft tacos cost $1.25
