Question

2*{12+3*[60-3*(27-4)*3)]}-5x=7

Answer 1

2*{12+3*[60-3*(27-4*3)]}-5x=7
2*{12+3*[60-3*(27-12)]}-5x=7
2*{12+3*[60-3*15]}-5x=7
2*{12+3*[60-45]-5x=7
2*{12+3*15}-5x=7
2*{12+45}-5x=7
2*57-5x=7
114-5x=7
5x=114+7
5x=121
x=121/5=24,2
succes la teme eu te-am ajutat pe ultima suta de metri ca trebuie sa ma duc la munca :)

Answer 2

2*{12+3*[60-3*(27-4)*3)]}-5x=7
2*{12+3*[60-3*23*3)]}-5x=7
2*[12+3*(60-207)]-5x=7
2*[12+3*(-147)]-5x=7
2*(12-441)-5x=7
2*(-429)-5x=7
-858-5x=7
5x=-865
x=-173
