Y=2x+5
sub 2x+5 for y in other equaiton
10x+3(2x+5)=19
distribute
10x+6x+15=19
minus 15 from both sides
16x=4
divide both sides by 16
x=1/4
sub back
y=2x+5
y=2(1/4)+5
y=1/2+5
y=5.5=11/2
solution is (1/4,11/2) or in decimal, (0.25,5.5)

The total volume of clay Dominic has is the volume of the block; length⋅width⋅height. That's 24.5 ⋅ 12.5 ⋅ 8 = 2450 inches cubed.
We'll divide the total volume of clay Dominic has by the required clay per vase to find how many vases he can make: 2450 ÷ 50 = 49 vases.
Dominic can make a maximum of 49 vases.
