#7) Solve 8c - 3c + 3 = 13.
nordsb [41]

Hello!

\large\boxed{c = 2}

8c - 3c + 3 = 13

Begin by combining like terms:

5c + 3 = 13

Subtract 3 from both sides:

5c + 3 - 3 = 13 - 3

5c = 10

Divide both sides by 5:

5c/5 = 10/5

c = 2.

Solve for ;x+20/2=3x
Alchen [17]
<span>x in (-oo:+oo)

(x+20)/2 = 3*x // - 3*x

(x+20)/2-(3*x) = 0

(x+20)/2-3*x = 0

(x+20)/2+(-3*2*x)/2 = 0

x-3*2*x+20 = 0

20-5*x = 0

(20-5*x)/2 = 0

(20-5*x)/2 = 0 // * 2

20-5*x = 0

20-5*x = 0 // - 20

-5*x = -20 // : -5

x = -20/(-5)

x = 4 so x= 4</span>
