Question

Is the equation 20z−5−12z=10z+8 one solution, no solution or infanate solutio?

Answer 1

Answer:

One solution.

Step-by-step explanation:

We have been given an equation $20z-5-12z=10z+8$. We are asked to find the number of solutions for our given equation.

Let us solve our given equation. Upon combining like terms, we will get:

$20z-12z-5=10z+8$

$8z-5=10z+8$

$8z-10z-5=10z-10z+8$

$-2z-5=8$

$-2z-5+5=8+5$

$-2z=13$

$\frac{-2z}{-2}=\frac{13}{-2}$

$z=-\frac{13}{2}$

Therefore, our given equation has only one solution.
