What is the solution to the system of equations?

use the substitution method.

y=−3x+1

2x+5y=18

enter your answer in the boxes.

  (-1, 4)

Step-by-step explanation:

It is convenient to use the expression for y that the first equation gives. Put that in the second equation.

  2x +5(-3x+1) = 18

  2x -15x +5 = 18 . . . . eliminate parentheses

  -13x = 13 . . . . . . . . . . collect terms, subtract 5

  x = -1 . . . . . . . . . . . . . divide by -13

Now, we can use this value of x in the first equation to find y.

  y = -3(-1) +1 = 4

The solution is (x, y) = (-1, 4).

(-1, 4)

Step-by-step explanation:

What you do is it tells you to use the substitution method so you take the first equation and substitute it into the y in the second equation.

2x+5(-3x+1)=18

2x-15x+5=18

-13x+5=18

-13x=13

x=-1.

You will then take the -1 and put it into the x in the first equation to get y.

y=-3(-1)+1.

y=3+1

y=4.

(-1, 4) is your answer.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
