Note the equal sign, what you do to one side, you do to the other side. Isolate the variable z.
First, subtract 3z and add 6/4 to both sides
4z (-3z) - 6/4 (+6/4) = 3z (-3z) + 1 (+6/4)
4z - 3z = 1 + 6/4
Simplify. Note that 1 = 4/4.
z = 4/4 + 6/4
Simplify. Combine like terms
z = 10/4
Simplify. Change the improper fraction into mixed fraction and simplify.
z = 10/4 = 2 2/4 = 2 1/2

Answer:
Step-by-step explanation:
Factor x3−4x2−9x−36
Cannot factor
<span>We simplify the equation to the form, which is simple to understand
<span>7x-1/2(8x+4)=6
</span></span><span>Simplifying:
<span>7x-0.5*(8x+4)=6
</span></span><span>Reorder the terms
<span>7x+(-4x-2)=6
</span></span><span>Remove unnecessary parentheses
<span>+7x-4x-2=+6
</span></span><span>We move all terms containing x to the left and all other terms to the right.
<span>+7x-4x=+6+2
We simplify left and right side of the equation.
<span>+3x=+8
We divide both sides of the equation by 3 to get x.
<span>x=2.66666666667</span></span></span></span>
