Solve this equation<br> y= 2x<br> x= -y + 6
zubka84 [21]

The solution is x = 2 and y = 4

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

y = 2x -------- eqn 1

x = -y + 6 ----------- eqn 2

We can solve the system of equations by substitution method

<em><u>Substitute eqn 1 in eqn 2</u></em>

x = -2x + 6

Move the variables to one side and constants to other side

x + 2x = 6

3x = 6

Divide both sides of equation by 3

x = 2

<em><u>Substitute x = 2 in eqn 1</u></em>

y = 2(2)

y = 4

Thus the solution is x = 2 and y = 4

Draw the graph of the equation 3x-4y=12 from the graph find the value of y when x= 8​
lutik1710 [3]

Answer:

y = 3

Step-by-step explanation:

3x - 4y = 12

3(8) - 4y = 12

24 - 4y = 12

- 4y + 24 = 12

- 4y + 24 - 24 = 12 - 24

- 4y = - 12

- 4y ÷ - 4 = - 12 ÷ - 4

y = 3

<em><u>Slope</u></em><em><u>:</u></em> \frac{3}{4}

<em><u>y - intercept</u></em><em><u>:</u></em> (0, - 3)
