Add 8 to both sides
-4a /5= 10
Multiply both sides by 5
-4a= 50
A= - 12.5
Simplify both sides of the equation.
−3f=6
Divide both sides by -3.
−3f/−3 = 6/−3
f=−2
Answer:
f=−2
Answer:
3x-6=x+9
so it will be equation solve x you will get it
Since they are simmilar we will then have the following relationships.

Now, we solve for x, as follows:

The expression goes along the lines of. 15 is to 10 what 9 is to x, with this as was done we solve for x and determine it's value, that since they keep proportionality.
