Answer:
The solution is (1, 2)
Step-by-step explanation:
The expression 4 - 2x is equivalent to y. Thus, we can eliminate y by substituting 4 - 2x for y in 3x + 2y = 7:
3x + 2(4 - 2x) = 7, or
3x + 8 - 4x = 7
Combining like terms, we get:
-x = - 1, or x = 1. If x = 1, then (from y = 4 - 2x) y = 4 - 2(1) = 2
The solution is (1, 2)
