-22 = 6x + 4<br> Hehehhe I need help agaaaaiiin
UkoKoshka [18]

Hey there!

Answer:\boxed{x=\frac{-13}{3}}

Explanation:

-22=6x+4

Let's start off with flipping the equation.

6x+4=-22

Now we need to subtract 4 from both sides of the equation.

6x+4-4=-22-4\\6x=-26

Now in our third/last step, we will divide both sides by 6.

\frac{6x}{6}=\frac{-26}{6}

x=\frac{-13}{3}

\boxed{x=\frac{-13}{3}}\text{ is the answer.}

Hope this helps!

Which is an equation of the line with slope that contains (–4, 7)?
MrMuchimi

Answer:

Because you did not give the slope, we cannot get the exact equation. However, using m as a substitute for slope, the point-slope form would be y - 7 = m(x + 4)

Step-by-step explanation:

We can find this equation through the use of the base form of point-slope form. Then we can plug in the point where we see fit.

y - y1 = m(x - x1)

y - 7 = m(x + 4)
