What is the solution to the system of equations?

Tatiana [17]

If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
y = 1
_______________
1 = –5x + 3
5x = 3 - 1
5x = 2 /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1).

Simplify -3x -y =-24 y = 3x

solmaris [256]

Answer:

x = 4

y = 12

Step-by-step explanation:

-3x - y = -24

y = 3x

Substitute for y in the first equation

-3x - (3x) = -24

-6x = -24

Divide by -6

x = 4

y = 3(4)

y = 12
