Question

multimea solutiilor ecuatiei 5 [2 (3|2x -5 |-11)-13]-27=8 va rooog!!!!Va dau coroana promit

Answer 1

5[2(3I2x-5I-13]=35
2(3I2x-5I-11)-13=35/5=7
2(3I2x-5I-11)=7+13=20
3I2x-5I-11=20/2=10
3I2x-5I=10+11=21
I2x-5I=21/3=7
2x-5=7   rezulta x=12:2=6
si 2x-5=-7, rezulta x=-1....deci multimea solutiilor e {-1;6}
