Question

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

Answer 1

$\bf2x+3y=13$

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 $\boxed{\bf(2,3)}$

Answer 2

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