Answer:
i'm sorry but where's the question?
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-6y + 4y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)

Step-by-step explanation:
Answer:
One. It is a = 7/3
Step-by-step explanation:
Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:
3a - 6 = 1
Adding 6 to both sides, we get:
3a = 7.
Dividing both sides by 3, we get
a = 7/3.
This equation has ONE solution, which is a = 7/3.
