Good. You could further describe how to 'bring' the like terms to one side, e.g. by adding "7" to both sides to balance the equation.<br />You are also right to say that the "x is equal to 7" though on the slide you put down "7=x". Remember to rewrite so that "x=7".<br /><br />Part (ii): The answer is correct. On the other hand, need to note that " cm^2 " should be read as "square centimetre" instead of "cm square".<br /><br />Part (iii): As it's area, you'll need to convert the length and breath, hence, it should be dividing by "100" twice. Answer should be 0.023 cm^2.LOH Kwai Yinhttp://www.blogger.com/profile/06503397685892227762noreply@blogger.com
