Treat the > as an = and solve the equation as you normally would. So for the inequality 7x+2 > 2x-3, pretend it was 7x+2 = 2x-3 and solve that. Just make sure you always replace where you'd write an...

There are two ways to solve the equation. One is to simply factorise it and the other is to use the formula provided in the formula booklet. The second method is probably easier when there isn't a nice ea...

4.28 rounds down to 4; sqrt(99) is approximately 10; 7.83 rounds up to 8

So an appropriate estimate would be:

(4x10)/8 = 40/8 = 5

-13 x + 7 > 2 -13 x > -5 x < 5/13

Remember multiply or divide a number by a negative number, you switch the inequality sign

This question can be solved in two ways. One way is to divide the whole equation, both sides by 3, which gives x-2=7. Then add 2 to both sides to give x=9. Another way is to work out the left hand side of...
