Question

A set of equations is given below:

Equation A: e = 4f + 1
Equation B: e = 3f + 5

Which of the following is a step that can be used to find the solution to the set of equations?

4f + 1= 3f
4f = 3f + 5
4f + 5 = 3f + 1
4f + 1 = 3f + 5

Answer 1

@Luigi0210 plz

Answer 3

Since e=4f+1 and e also =3f+5, you can set the equations equal to one another:

\(4f+1=3f+5\)

Answer 4

can you help with a few more @Luigi0210

Answer 5

A set of equations is given below:

Infinitely many solutions

Answer 7

@robtobey can u help ?

Answer 8

if you do the first few steps and try and cancel out a variable, you would see that you get 0=-6 or something.. which is no solution.

Answer 9

No problem (✿◠‿◠)

Answer 10

@luigi0210

Two lines, C and D, are represented by the equations given below:

Line C: y = x + 14
Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why?

(6, 20), because both lines pass through this point
(6, 20), because the point does not lie on any axis
(3, 11), because one of the lines passes through this point
(3, 11), because the point lies between the two axes

Answer 12

Sorry about that, OS is.. not the best.

Anyways, you should do the same thing and set them equal to each other:

\(x+14=3x+2\)

Get x to the right and numbers to the left:
\(12=2x\)

Now get x:
\(6=x\)

Now just plug in 6 and solve:
y=(6)+14

Solution: \((x, y) ===> (6, --) \)

Answer 13

@Luigi0210

Two lines, A and B, are represented by the equations given below:

Line A: x + y = 2
Line B: 2x + y = 4

Which statement is true about the solution to the set of equations?

There are infinitely many solutions.
There are two solutions.
There is one solution.
There is no solution.

Answer 14

You have a lot of questions xD

Anyways, solve it: 2x+(-x+2)=4
x=2

2+y=2
y=0

So it has one solution :P
