Inequalities can be treated just like equations with one major difference - if you multiply or divide both sides using a negative number then the Inequality Sign is reversed. This doesn't actually apply in these questions.
1) 8x + 9 < 9x - 8...add 8 to both sides and subtract 8x from both sides
17 < x...it's normal practise to put x as the subject.
X > 17
2) x - 6 > 2x - 7...add 7 to both sides and subtract x from both sides
1 > x...and putting x as the subject
x < 1
1) 8x + 9 < 9x - 8...add 8 to both sides and subtract 8x from both sides
17 < x...it's normal practise to put x as the subject.
X > 17
2) x - 6 > 2x - 7...add 7 to both sides and subtract x from both sides
1 > x...and putting x as the subject
x < 1
