Subtract 5 from both sides
a/-8 = 4/7 - 5

simplify 4/7 - 5 to 31/-7
a/-8 = 31/-7

multiply both sides by 8 
-a = 31/-7 x 8

simplify 31/7 x 8 to 248/7
-a = 248/7

multiply both sides by -1.
The answer is a = 248/7

Y=6x - 11 -2x - 3y = -7
Ray Of Light [21]
<h2>Therefore x=2 and y= 1</h2>

Step-by-step explanation:

Given equations are

y = 6x -11                    and         -2x -3y = -7.........(2)

⇒y - 6x = -11.......(1)

Equation (2)× 3 - Equation (1)

-6x -9y -(y-6x) = -21 -(-11)

⇔-6x -9y-y+6x=-21+11

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

1 = 6x -11

⇔x =2

Therefore x=2 and y= 1
