Solve for x in X-2 (x=8)
Substitute X=8 into 3x - 6y =18 (24-6y=18)
Solve for y in 24-6y=18 (y=1)
X=8 and y=1

Answer:
1.) 9.9
2.) 15.6
Step-by-step explanation:
1.) Consider triangle AEH
AEH is a right angle triangle as ∠AEH = 90°
AH is the hypotenuse of the triangle.
Applying Pythagorean theorem

substituting values as given in the question:

∴ EH≈9.9
2.) Consider triangle CDF
CDF is a right angle triangle as ∠CDF = 90°
CF is the hypotenuse of the triangle.
Applying Pythagorean theorem

substituting values as given in the question:

∴ DF≈15.6
Say your function is
f(x) = 2x + 3
If f(x) is 2 & you want to find x, replace f(x) with 2:
2=2x+3
And solve for x:
-1=2x
x=-1/2
Hope this helps!
