8x−5x+4−x=Ax+8. Anyone know
lora16 [44]

Answer:

a = \frac{2x-4}{x}

x = \frac{4}{-a+2}

Step-by-step explanation:

Let's solve for a.

8x−5x+4−x=ax+8

Step 1: Flip the equation.

ax+8=2x+4

Step 2: Add -8 to both sides.

ax+8+−8=2x+4+−8

ax=2x−4

Step 3: Divide both sides by x.

Let's solve for x.

8x−5x+4−x=ax+8

Step 1: Add -ax to both sides.

2x+4+−ax=ax+8+−ax

−ax+2x+4=8

Step 2: Add -4 to both sides.

−ax+2x+4+−4=8+−4

−ax+2x=4

Step 3: Factor out variable x.

x(−a+2)=4

Step 4: Divide both sides by -a+2.

Hope this helps!

Find the equation of the line that passes through the following points. Write the equation in​ slope-intercept form. ​(-4​,-8​)
scZoUnD [109]
Let's start with the x coordinates.

-8 is on the left, and -4 to the right, so that will help organize this.

the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.

rise/run so 1/4 is the slope.

y=(1/4)x - 7
