Answer:

x=1 and y=-8/3

Explanation:

The easiest way to solve this is by substitution because the first equation is already in slope-intercept form.

First, take y= 4/3x -4 and substitute it into the second equation as follows: 6x + 3(4/3x -4) = -2

Next, simplify that equation to get 6x + 12/3x -12 = -2.

After that, combine all like values: 10x - 12 = -2.

Finally, add 12 to each side and divide by 10 to get x=1.

To find the y-value, substitute x=1 into either equation and solve for x (I'm choosing the first equation). y= 4/3(1) -4

In order to make simplifying this easier, I find that -4 = -12/3.

Finally, simplify: y= 4/3 - 12/3 = -8/3.

The solution to the system of equations is (1, -8/3), or x=1 and y=-8/3.

Answer:

x = 1 and y = -8/3

Explanation:

  • In order to solve this, insert equation 1 into 2

solve for x


\sf 6x+3\left((4)/(3)x-4\right)=-2


\sf 6x+4x-12=-2


\sf \rightarrow 10x = -2 +12


\sf \rightarrow 10x = 10


\sf \rightarrow x = 1

solve for y


\hookrightarrow \sf y = (4)/(3) x-4


\hookrightarrow \sf y = (4)/(3) (1)-4


\hookrightarrow \sf y=-(8)/(3)
