Question

How many solutions does the following equation have? 20z – 5 – 12z = 10z + 8

Answer 1

The equation $20z-5-12z = 10z + 8$ have one solution i.e $z=-\frac{13}{2}$

Step-by-step explanation:

Finding the solutions of the equation:

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

Solving:

$20z-5-12z = 10z + 8\\8z-5=10z+8\\Adding\,\,5\,\,on\,\,both\,\,sides\\8z=10z+8+5\\8z=10z+13\\Adding\,\,-10z\,\,on\,\,both\,\,sides\\8z-10z=13\\-2z=13\\z=\frac{13}{-2} \,\,or\\z=-\frac{13}{2}$

The equation $20z-5-12z = 10z + 8$ have one solution i.e $z=-\frac{13}{2}$
