Answer:

(-6,9)

Step-by-step explanation:

That y = 9 is given. Thus, substitute 9 for y in x + y = 3, obtaining x + 9 = 3.

Subtracting 9 from both sides, we get x = -6. Then the solution is (-6,9).

Alexxx [7]

Answer:

x = 3

Step-by-step explanation:

5(2 - x) = 7x - 26

Distribute;

10 - 5x = 7x - 26

Add 5x to both sides;

10 = 12x - 26

Add 26 to both sides;

36 = 12x
