Answer:
We need to flip the symbol at the end of the question.
answer: x<= 6.5
Stepbystep explanation:
Given inequality: 2(x4)+5<=4(x4)
Distribute: 2x8+5<=4x16
Undo a constant term from left side: 2x3<= 4x16
Combining the like terms: 2x4x<=16+3
Undo the coefficient term from left: 2x<=13
Undo the variable term: x<=(13/2)=6.5
Now checking if this is write: Lets take x=6<6.5
Put x=6 in given inequality:
2(64)+5<=4(64)
2(2)+5<=4(2)
4+5<=8
9<=8 (which is not possible)
so we need to flip the inequality
2(x4)+5>=4(x4)
9>8
