Question

Solve for z
3z-2z=17
z=

Answer 1

z = 17

Explanation:

3z-2z=17

z = 17

Answer 2

z = 17

Explanation:

Hi! Our task is to solve the equation
`\sf{3z-2z=17}`.

So, first, we will simplify the left-hand side by combining the like terms:

`\sf{z=17}`, which is our final solution.

Therefore, the value of z is
`\bf{z=17}`.

`\underline{\underline{\bigstar\qquad\boldsymbol{\sf{Checking\:Your\:Solution}}\qquad\bigstar}}`

We will now make sure that z = 17 is indeed the solution to this equation. The way we'll do that is we'll substitute 17 for z:

`\twoheadrightarrow\qquad\bf{3\cdot17-2\cdot17=17}`

`\twoheadrightarrow\qquad\bf{51-34=17}`

`\twoheadrightarrow\qquad\bf{17\stackrel{\checkmark}{=}17}`

A true statement indicates that z = 17 is indeed a solution of this equation.
