Answer:
f=13/9
Step-by-step explanation:
f-8/9=5/9
solution
f=5/9+8/9
f= 5+8/9=13/9
Ok so first we find the equation that equals one variable.
2y = -x + 9
3x - 6y = -15
We solve for y.
2y = -x + 9
y = -x/2 + 9/2
Then we plug in this y value into the other equation to keep only one variable so we can solve for it.
3x - 6y = -15
3(-x + 9/2) - 6y = -15
-3x + 27/2 - 6y = -15
-9y + 27/2 = -15
-9y = 3/2
-y = 3/18
y = -3/18
Then we plug in this numerical y-value into the first equation which we found out by solving an equation for y.
y = -x/2 + 9/2
-3/18 = -x/2 + 9/2
-84/18 = -x/2
-x = 9 1/3
x = -28/3
Your answer would be (-28/3, -3/18)
Hope this helps!

Answer:
The moon equals 7
and the stars equal 4
Step-by-step explanation:
Equation 1:
(substitute the symbols for the numbers)
7 + 1 = 4 + 4 (<< This is correct, both sides equal 8)
Equation 2:
(again, substitute the symbols)
7 = 3 + 4
That is correct.
