4(x-5) +2 =x+3 <br><br> I need help on this ! I don’t get it picture above !
algol [13]

Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3       Subtract x from each side. Now, we can get x to only one side.

<u>-x       -x</u>

3x-18=-3         Add 18 to both sides.

  <u>+18 +18</u>

3x=-15            Divide both sides by 3.

<u>/3   /3</u>

x=-5

I hope this helped you!! Have a great day c:

y = mx + b

3) 5 = m(8) = b

4) your slope is negative form the why it pointing

5) in this case your slope is 1/3

6) so now you can do your first step now that you have your (y,x) and slope (your solving for (b)

7)

5 = 1/3 (8) + b

5 = 2.6 + b

5 = 2.6

-2.6
