Solve the system by substitution.

-6x+8y=-18

3x=y

x = - 1, y = - 3

Step-by-step explanation:

-6x + 8y = - 18 (1)

3x = y (2)

From equation 2,

y = 3x

Now, substitute the value of y into equation 1 as shown below:

-6x + 8y = - 18

-6x + 8 (3x) = - 18

-6x + 24x = - 18

18x = - 18

Divide both side by the coefficient of x i. e 18

x = - 18/18

x = - 1

Substitute the value of x into equation 2 as shown below:

y = 3x

y = 3 (-1)

y = - 3

Therefore, x = - 1, y = - 3

Answer: (-1,-3)

Step-by-step explanation:Solve for the first variable in one of the equations, then substitute the result into the other equation.
