Answer:
3
Step-by-step explanation:
Answer:
a = 1
Step-by-step explanation:
<u><em>The given equation is:</em></u>
=> 5x+y = 8
Also,
Point = (x,y) = (a,3)
So, x = a , y = 3
<u><em>Putting this in the above equation</em></u>
=> 5(a)+3 = 8
=> 5a = 8-3
=> 5a = 5
<em>Dividing both sides by 5</em>
=> a = 1
-17/4 is the correct answer
In decimal it’s -4.25
Answer:

Given equations:
<u>Make x the subject in equation 1</u>:
<u>Substitute this into equation 2</u>:
2(y - 3) - 7y = -14
2y - 7y = -14 + 6
-5y = -8
y = -8/-5
y = 1.6
Then x = y - 3
= 1.6 - 3
= -1.4
Solution: (x, y) ⇒ (-1.4, 1.6)
