10(x+2) -(2x-9)=30; 10x+20-2x+9=30 paying attention to the sign change when solving the brackets; 8x+29=30; 8x=1 separating in order to find out x; x=1/8
When we factorise, we are trying to put a long expression into a couple of brackets to make it neater and easier to work with. It is the opposite to multiplying out brackets. To start off with, we will fa...

So we know that our equation is: X2 - 10X +17 = 0. STEP 1: rearrange this equation to get x on one side: X2 - 10X = -17. Lets call this, "equation 1". STEP 2: Understand th...
First you must figure out your estimates, in this case you can round 2162 down to 2000 and 12.37 to 10 to make your solutions easier. First you must calculate the total number of hours it is going to take...
