1. krish

13x = 43 x= 43/13

2. kushashwa

see here u can find the answer by TRIAL AND ERROR METHOD WHICH WILL TELL U THAT THE VALUE OF x IS 5 OR -3

3. AnwarA

It has two solutions, either \(3x-3=12 \implies 3x=15 \implies x=5 \) or \(3x-3=-12 \implies 3x=-9 \implies x=-3\).

4. AnwarA

Guys, is latex working with you?!

5. kushashwa

have u understood this question

6. Chandman

Whats the trial and error method?

7. AnwarA

You shouldn't use trial and error. The solution is to set 3x-3 equal to 12, and then set it equal to -12. Because |12|=|-12|=12.

8. krish

trial and error is try yourself

9. kushashwa

trial and error method is also known as HIT AND TRIAL METHOD WHICH MEANS TO PUT VALUES ON THE THE PACE OF VARIABLE/S

10. kushashwa

WHY ANWAR WE CAN USE TRIAL AND ERROR HERE

11. AnwarA

We can! But it's not very easy to find the right answer, especially when the expression is much complicated.

12. kushashwa

yes but this question can be solved by TRIAL AND ERROR
