-3x + 2c = -3, solve for x
zzz [12365]

Answer:

x=2c/3+1

Step-by-step explanation:

First, subtract 2c from both sides.

−3x=−3−2c

The equation has been transformed into standard form.

−3x=−2c−3

Next, divide both sides by −3.

-3x/-3=-2c-3/-3

Dividing by −3 negates the multiplication by −3.

x=-2c-3/-3

Finally, divide −3−2c by −3.

x=2c/3+1

AnnZ [12381]
The greatest common factor shared by 32 and 44 is 4. This is factored out as follows: 4(8 + 11) = 4(8 + 11), which appears strange to me, but that's how most textbooks illustrate the factoring process.
