Question

Solve the following inequality. 2( z + 1 ) - 4(z - 4) ≤ 2(z + 5)

Answer 1

Basically what you would do is 2z+2-4z+16< 2z+10. next thing you would do is combine like terms to get. -2z+18<2z+10. then you would combine like terms to get -4z<-8. then you divide by 4 to get z_<-2

Answer 2

Do you need the graph? or the value of each variables?
