Question

Subtract 10 from v and multiply 5 to the difference

Answer 1

Step-by-step explanation:

Let the no be x

Multiply by 10 gives 10x.

Divide by 5 gives 10x/5=2x;

Add 10 gives, 2x+10

Subtract 20 gives ,2x+10-20= 2x-10

The whole thing is equal to 10

So we have 2x-10=10.

2x=20

X=20/2

×=10.
