The answer for question (1) 16%
Answer:
Factors of the constant term
Step-by-step explanation:
Answer:
x = -19; y = 25/3
Step-by-step explanation:
Step 1: solve the equation with only one variable
Isolate the variable (x)
x + 10 = -9
x = -9 - 10
x = -19
Step 2: input new information into the other equation
If x = -19, then:
2(-19) - 6y = 12
Isolate the variable (y)
-38 - 6y = 12
-6y = 12 + 38
-6y = 50
y = 50 ÷ 6
y = 50/6
Simplify
y = 25/3
Question # 17 Solution
Answer:

Step-by-step Explanation:
The given expression

And we have to solve for x₁
So,
Lets solve for x₁.

Multiply both sides by x₂ - x₁




Divide both sides by -m


Therefore, 
Question # 23 Solution
Answer:

Step-by-step Explanation:
The given expression

And we have to solve for n
So,
Let's solve for n.

Multiply both sides by b.

Factor out n.

Divide both sides by -b + x.


Therefore,
