<u><em>The complete question is</em></u>
Translate to a system equation
Twice a number plus three times a second number is negative one. The first number plus four times the second number is two.
Call the first number m and the second number n
Let
m ----> the first number
n ----> the second number
we know that
----> equation A
---->
----> equation B
Solve the system by substitution
Substitute equation B in equation A
solve for n
<em>Find the value of m</em>
---->
therefore
The first number is -2 and the second number is 1
