Question

What is the answer to
2x + 3y = 13
x = 2

Answer 1

2x + 3y = 13
2(2) + 3y = 13
4 + 3y = 13
- 4 - 4
3y = 9
3 3
y = 3

Answer 2

`\bf2x+3y=13`

Plug in x = 2:


`\bf2(2)+3y=13`

Multiply:


`\bf4+3y=13`

Subtract 4 to both sides:


`\bf3y=9`

Divide 3 to both sides:


`\bf~y=3`

So our solution is
`\boxed{\bf(2,3)}`
