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

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)
