So first step: simplify like terms. Since you have two like terms on the same side then you just add them together. Your equation now looks like this: -9=11x+24. Then you subtract 24 from both sides to get -33=11x. Divide both sides by 11(the coefficient of x), and you get -3=x. I hope my steps are clear enough and this is helping you. If you really don’t get it you should ask your teacher. It would really help you.

-9 = 4 + 11x + 20

Combine like terms on the right side of the equation.

-9 = 24 + 11x

Subtract 24 from both sides.

-33 = 11x

Divide both sides by 11.

x = -3

7. Write the equation of a line which passes through the points (-3,5) and (6,23)
faust18 [17]

Answer:

answer to the equation is

y = 2x + 11

Step-by-step explanation:

y = mx + b

first find the slope of the line using the two points

slope \: m =  \frac{y2 - y1}{x2 - x1}  =  \frac{23 - 5}{6 - ( - 3)}   \\ =  \frac{18}{9}  \\ slope \: m = 2

substitute 2 for m and use one of the points for x and y and solve for b

5 = 2( - 3) + b \\ 5 =  - 6 + b \\ 5 + 6 = b \\ b = 11

Now that you found b, the y-intercept, you can substitute that into the equation for your line

y = 2x + 11
