If A+ B = 76
A-b = 38
A ÷ B =?

For this case we have the following system of equations:

Solving the system of equations we have:

1) We subtract equation 1 with equation 2:

2) We clear the value of B:

3) We substitute The value of B in equation 2 and obtain the value of A:

Then, the value of the division of both numbers is:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
