Answer:
The ordered pair (1, 2) is a solution to the system of linear equations.
1 Subtract 22 from both sides
13x=4x+38-213x=4x+38−2
2 Simplify 4x+38-24x+38−2 to 4x+364x+36
13x=4x+3613x=4x+36
3 Subtract 4x4x from both sides
13x-4x=3613x−4x=36
4 Simplify 13x-4x13x−4x to 9x9x
9x=369x=36
5 Divide both sides by 99
x=\frac{36}{9}x=
9
36
6 Simplify \frac{36}{9}
9
36
to 44
x=4x=4
