Question

Solve by trial and error method :

a) 5 x - 3 = - 8.​

Answer 1

x = -1

Explanation:

5x - 3 = -8

Trial and error means make a guess and then see if it is right and if not make another guess

Let x =0

5*0 -3 = -8

-3 = -8

We need a number that is negative for x

Let x = -1

5(-1) -3 = -8

-5-3 = -8

-8 = -8

x = -1
