Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = 
x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x + x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
The correct answer is C. 4.
Typically, we look to multiply by the bottom number (the denominator) in order to get fractions to cancel out. If we multiply 1/6 by 6, we get just 1, which is why we do it.
In this problem, you have two different denominators, 2 and 4. If you multiply them all by 2, the term -3/4m will still be a fraction.
-3/4m * 2 = -3/2m
As a result, we must try 4 instead. This causes all of them to cease being a fraction. Even the one with 2 as a denominator.
-1/2 * 4 = -2
