If the equation is -(2/3) x - (1/4) y = 1/3, it is a straight line, so you can use some special points to identify the graph.

It is easier is you solve the equation for y:

(1/4)y = - 1/3 - (2/3) x

y = (-4/3) - (8/3)x

That is the slope -y-intercept form of the equation.

That means that the slope is -8/3, and the y-intercept is -4/3.

Use this points to identify the graph:

x = 0 => y = - 4/3 ---> (0, - 4/3)

y = 0 => x = - 1/2 -----> (-1/2, 0)

Now you can punt those two points on the graph and draw the line that joins them.

With this procedure you can find the graph of any straight line.

5(x-2) + X = 6(x+3) -4X
mezya [45]

Answer:

8x-7

Step-by-step explanation:

5(x-2)+X=6(x+3)-4x

You would need to use the distributive property first to distribute 5 and 6.

5x-10 + X= 6x+3-4x

You would then need to combine like variables.

5x+x+6x-4x=8x

-10+3=-7

Then you would just recreate the expression.

8x-7
