What is 3x-2y=11
X+2y=9 using substitution

(5, 2)

Step-by-step explanation:

We have hte equations:

3x - 2y = 11

x + 2y = 9

Solving by substituting simply means writing one variable in terms of the other, plugging that into the other equation, and then solving.

x + 2y = 9

x = 9 - 2y

Plug in 9 - 2y for x in the first equation:

3x - 2y = 11

3 * (9 - 2y) - 2y = 11

27 - 6y - 2y = 11

27 - 8y = 11

16 = 8y

y = 2

Use this to find x:

x = 9 - 2y = 9 - 2 * 2 = 9 - 4 = 5

The solution is (5, 2).
