Question

Will fan and metal!
Just say a,b,c,or d

Answer 1

A set of equations is given below:

Equation E: a = 5b + 1
Equation F: a = 3b + 4

Which statement describes a step that can be used to find the solution to the set of equations?

Equation F can be written as 5b + 1 = 3b + 4.
Equation F can be written as b + 1 = 3b + 4.
Equation F can be written as a = 3(a − 1) + 4.
Equation F can be written as a = 5(a − 4) + 1.

Answer 2

and the other one is

Answer 3

A student is trying to solve the system of two equations given below:

Equation P: y + z = 6
Equation Q: 8y + 7z = 1

Which of the following is a possible step used in eliminating the y-term?

(y + z = 6) ⋅ −8
(y + z = 6) ⋅ 7
(8y + 7z = 1) ⋅ 7
(8y + 7z = 1) ⋅ 8

Answer 4

help i am going to fail!

Answer 5

To approach the first question:
if y = 6x – 3 and y = 3x + 4
I can say that 6x – 3 = 3x + 4. Does that make sense?

Answer 6

If a = Something AND a = Something else
then

Something = something else

Answer 7

Substitute what a equals in the first equation for a in the second equation, that is your answer

Answer 8

For the second, they want you to use the technique of adding together the two equations to have one variable cancel out.

If you multiply the first equation by (-8), then you will have -8y in the first equation and +8y in the second equation.
Adding the two equations together eliminates the Y variable , (-8y+8y) = 0y
