Question

x=2y-3
2x-3y=-5

Answer 1

sub equation for x into second one and solve for x. this lets you solve x in terms of y.

Answer 2

\[x-2y =-3\]
\[2x-3y=-5\]

Answer 3

2(2y-3)-3y=-5
distribute
4y-6-3y=-5
+6 +6
4y-3y=1
1y=1
y=1

sub into other equation

x=2y-3
x=2(1)-3
x=2-3
x=-1

Answer 4

multiply 1st equation by -2 ==>
\[-2x +4y=10\]
adding the equations ==>
y =10 ==> x=17

Answer 5
