What do you mean exactly? I will help you if you provide more information.
7. is (4x+9)/7=f(x) because you switch the x and y and then solve for y.
f(x)=y
y=(7x-9)/4
x=(7y-9)/4
4x=7y-9
4x+9=7y
(4x+9)/7=y
Answer:
7
Step-by-step explanation:
To solve this problem we need to find x
First we need to do parenthesis
This means that the equation becomes 5x - 2x - 2 = x + 3x + 5
Next add or subtract, this simplifies it to 3x - 2= 4x + 5
After this bring the numbers on the right and the variables on the left
This means subtracting 4 on each side and adding 2 on each side
Now the equation becomes -x = 7
Lastly, put the negative on the right
x = 7
