5=5ax+1 please help, its due in an hour.<br><br> solve for x
RUDIKE [14]

Answer:

x= 4/5a

Step-by-step explanation:

5=5/ax+1

Step 1: Multiply both sides by a.

5a=a+5x

Step 2: Flip the equation.

a+5x=5a

Step 3: Add -a to both sides.

a+5x+−a=5a+−a

5x=4a

Step 4: Divide both sides by 5.

5x/5=4a/5

x= 4/5a

Hope this helps!

Tom's age is 5 more than twice Dic's age.
kvasek [131]
If we break the answer down, we can solve this pretty easily.
We can represent Dic's age with x.
Tom's age is 5 MORE (+5) than TWICE (2x) Dic's age (x)
Therefore, our answer is 5+2x (Five more than twice Dic's age)

The correct answer is C: 5+2x
