-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
24 ÷ (12-4) = 3
A and C also equal 3
Remember the order of operations! makes all the difference!

Answer:
from where we can find the value of x
Answer:
16
Step-by-step explanation:
-1 = -⅝ c + 9
Subtract 9 from both sides:
-10 = -⅝ c
Multiply both sides by 8:
-80 = -5c
Divide both sides by -5:
c = 16
