OpenStudy (anonymous):

13x = 43 x= 43/13

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

Guys, is latex working with you?!

OpenStudy (anonymous):

have u understood this question

OpenStudy (anonymous):

Whats the trial and error method?

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

trial and error is try yourself

OpenStudy (anonymous):

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

OpenStudy (anonymous):

OpenStudy (anonymous):

yes but this question can be solved by TRIAL AND ERROR
