Question

Solve the following system by subsittution

y=5x-4
y=6x

Answers

y = -3

y = 6

y = 0

y= - 24

Answer 1

y= -24

x= -4

Step-by-step explanation:

we can substitute the expression for y in the second equation with the expression for y in the first equation, since both expressions are equal to y:

y = 5x - 4 (equation 1)

y = 6x (equation 2)

Substituting equation 1 into equation 2, we get:

5x - 4 = 6x

Simplifying, we get:

-x = 4

Dividing both sides by -1, we get:

x = -4

Now that we know x, we can use either equation to find y. Let's use equation 2:

y = 6x = 6(-4) = -24

Therefore, the solution to the system of equations is (x, y) = (-4, -24).
