Question

Need answer 25 and answer 27

Answer 1

`\\ \bull\tt\dashrightarrow (-3)/(8)x-20+2x>6`

`\\ \bull\tt\dashrightarrow (-3)/(8)x+2x=6+20=26`

`\\ \bull\tt\dashrightarrow (-3+16)/(8)x=26`

`\\ \bull\tt\dashrightarrow (13)/(8)x=26`

`\\ \bull\tt\dashrightarrow x=26* (8)/(13)`

`\\ \bull\tt\dashrightarrow x=8(2)=16`

#27

`\\ \bull\tt\dashrightarrow 0.5x-4-2x\leqslant 2`

`\\ \bull\tt\dashrightarrow 0.5x-2x\leqslant=2+4=6`

`\\ \bull\tt\dashrightarrow -1.5x\leqslant 6`

`\\ \bull\tt\dashrightarrow x\leqslant(6)/(-1.5)`

`\\ \bull\tt\dashrightarrow x\leqslant 4`
