Answer:

x = -3

Step-by-step explanation:

You have the following equation:

3(2x+4)=-6\\

you first you distribution property in order to eliminate the parenthesis:

3*2x+3*4=-6\\\\6x+12=-6

next, you subtract 12 in both sides of the equation:

6x+12-12=-6-12\\\\6x=-18

Finally, you divide the equation by 6 and simplify:

\frac{6x}{6}=-\frac{18}{6}\\\\x=-3

hence, the solution to the equation is x = -3

The equation y minus 3 = negative 2 (x + 5) is written in point-slope form. What is the y-intercept of the line?
lubasha [3.4K]

Answer:

-7

Step-by-step explanation:

y-3=-2(x+5)

So we need to put this in slope-intercept form...

y - 3 = -2x -10  (You use the distributive property)

Then shift the -3 over to meet the other constant -10 by addition.

y - 3 = -2x -10

 +3          + 3

y = -2x -7      since y = mx + b is in slope intercept form m = slope and b = y intercept, therefore the y intercept is -7
