If the sum of a number and 9 is , the result is 7 less than the twice number. Find the number.

16

Step-by-step explanation:

This is the answer because:

1) First, build up an equation that will help you solve the question: x + 9 = 2x-7

2) Now, simplify the equation:

9 = x - 7

3) Finally, solve for x which is 16.

Hope this helps!

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
