For 7x3 and 28x2
Are those x’s multiplication? Or just an X
Answer and Step-by-step explanation:

Step 1: Add -3x to both sides


Step 2: Divide both sides by 2.


Answer:
<h2>y = -2x - 10</h2>
Step-by-step explanation:
The formula of a slope:

We have two points (-5, 0) and (-1, -8). Substitute:

The slope-intercept form of an equation of a line:

m - slope
b - y-intercpet
Put the value of the slope and coordinates of the point (-5, 0) to the equation of a line:

<em>subtract 10 from both sides</em>

Finally:

3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
