Write the co-efficent of x in -5/2xyz

The coefficient is simply -5/2.

An expression, in this case -5/2xyz, is made up of the coefficient and the variables. We can see that the only number that prefaces the variables is -5/2.

As a result, we can take away the variables and keep the number -5/2, which would be the coefficient.

Hope this helps.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
