Answer:
-x + 6 = 1 is the resulting equation when the expression for y in the second equation is substituted into the first equation 3x + y = 1 y = 6 - 4x . 5x = 10 is the result of adding the system of equations: 2x + y = 4 3x - y = 6 .Step-by-step explanation:

Answer:
r = -6.1
Step-by-step explanation:
-7.8 = 4.4 + 2r
To get r, you need to isolate the variable
Subtract the 4.4 from both sides
-7.8 - 4.4 = 4.4 + 2r - 4.4
4.4 cancels out on the right
-12.2 = 2r
Divide both sides by 2
-12.2/2 = 2r/2
-6.1 = r
Answer:
c=11d+1
Step-by-step explanation:
First, you should know how will 1 lesson cost. Eventually, 1 lesson costs $11.
c is for the cost.
11 is for the cost of 1 lesson.
d is for the lessons
1 represents (1 lesson, which costs $11)
