I need 10x+3y=19 and y=2x+5 solved algebraically

taurus [48]

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)
