Since 2z^2 is a factor fo 4z^3, it is automatically the GCF.

[object Object]

The GCF is 2z

4z + 3 = 6 + 2zSubtract 2z from each side of the equation:2z + 3 = 6Subtract 3 from each side:2z = 3Divide each side by 2:z = 3/2 = 1.5

There are a few ways to isolate a variable. First, add or subtract anything to get a monomial on one side containing the variable. Then divide by anything that is being multiplied to the variable. Here is an example: xy-4z=2z-4y solving for x xy=(2z+4z)-4y xy=6z-4y x=(6z-4y)/y

6xy^2z^2 over 6xy^4z^4 or 1 over y^2z^2

(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)

I used the matrix method to find the answer: x=4, y=-7, z=-5.

Well, you combine the like terms (-4z and 4z). -4z - 4z = -8z Now I'm not sure what to do after this because you haven't written the operation that comes before the 9, whether it's +, -, x, or /

z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5

post an equation first.
