the answer would be
because you would need to find the LCD, which in this case would be 56 and you solve from there.
Firstly you have to reduce the 4 variables to a double system of equation with only 2 variables.
Let's say, first we have to eliminate Z:
Take 1st & 3rd equation & multiply each term of the 1st by (- 1). One done you add up the 1st & the 3rd & you will get:
5W - 4x + 2y = - 18
Follow the same methodology to find another equation without z. Once done you will have a system of 2 equation with 2 variable easy to solve,
At the end you will find:
w = -3
x = -2
y = -1
z = 3
Answer:
A. -5m/5 does not equal m
Step-by-step explanation:
-5m/5 = -m, not m.
In step 2, both sides should be divided by -5, not by 5.
Answer: A. -5m/5 does not equal m
One hundred an two
