<u>Option C is correct </u><u>(y + z = 6) ⋅ −3</u>
What is a linear equation in math?
- A linear equation only has one or two variables.
- No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
- When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
As per the statement -
A student is trying to solve the system of two equations given below:
Equation P: y + z = 6 ....[1]
Equation Q: 3y + 4z = 1 ....[2]
Multiply the equation [1] by -3 to both sides we have;
-3 .( y + z = 6 ) ⇒ -3y -3z = -18..........(3)
Add equation [2] and [3] to eliminate the y-term;
z = -17
Therefore, the possible step used in eliminating the y-term is, (y + z = 6) ⋅ −3

A student is trying to solve the system of two equations given below: Equation P: y + z = 6 Equation Q: 3y + 4z = 1 Which of these is a possible step used in eliminating the y-term?
(y + z = 6) ⋅ 4
(3y + 4z = 1) ⋅ 4
(y + z = 6) ⋅ −3
(3y + 4z = 1) ⋅ 3

Answer:
Mom would required 1 lbs of Sugar and 4 lbs of water.
Step-by-step explanation:
Given:
Amount of Sugar syrup Mom wants to make = 5 lbs
Percentile amount of syrup she needs to make = 20%
Solution:
Let amount of sugar to make 20% syrup be 'x'.
So by definition of proportion we get;
Now Multiplying both side by 5 we get;
So we can say that;
Amount of water = 
Hence Mom would required 1 lbs of Sugar and 4 lbs of water.
The answer is 111
Calculate square root of 1 to get 1
Multiply 111 x 1
=111
