very urgentttt

Answer 1

Step-by-step explanation:

So let x = the first number and let y be the "other" number.  

So the first statement means that x = 2y + 7 -- 7 more than twice the other number.  

And the second statement says that x + y = 31.  

So that gives you two equations with two unknowns:

x = 2y + 7

x + y = 31  

So you just have to solve these.  

Since the first equation gives you an easy expression for x, just substitute that into the second equation:

x + y = 31

(2y + 7) + y = 31

3y + 7 = 31

3y = 24

y =  8

Since the sum of the two numbers is 31, x must be 23.
