Is it supposed to be 3*2+4x=1 (The star means to multiply). If so do the following.

3*2+4x=1
Multiply 3*2
6+4x=1
Subtract 6 from both sides
4x= -5
Divide by 4
x= -1.25

Over here.. We have to make x as the subject.
Which means...You'd have to multiply 3 and 2 which is 6...6+4x=1 After which you shift 6 to the other side... 4x=1 -6 ..Whixh concludes 4x is ...Wait.. is there an error in the question?.. Shouldn't it be 3x+2+4x=1?

ki77a [65]
The format is y = mx + b
where y would be your C
x would be your M
m would be the price per mile (2.20)
and b would be your initial fee (2.75)

put this together in that format and we get
C = 2.20M + 2.75

SoIve the system of equations by elimination. (Addition)<br> 1)-2x + 4y = -22<br> 2x + 8y = –26
Rufina [12.5K]

Answee:

We have these two equations:

-2x +4y =-22

2x + 8y -26

We need to try to get the same number multiplying both x or y, I think we can make the 2 of the first equation negative, for that, we multiply all the equation by -1:

2x + 8y =-26  ---- -2x - 8y =26

Now we have this:

-2x +4y = -22

-2x -8y = 26

Now e substract both equations:

-2x - (-2x) +4y -(-8y) = -22-26

12y = -48

Y = -48/12 = -4

And we replace to get x

-2x + 4y = -22

-2x +4*(-4)=-22

-2x - 16 = -22

x= -6/-2 =3
