Answer:
substitution
Step-by-step explanation:
We assume the two equations are ...
You are given an expression for x. Using that in the second equation will result in an immediate solution for y.
... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x
.. y +8 = 11
... y = 3
... x = 2·3 +4 = 10
The solution is (x, y) = (10, 3)
