Multiply the -9 using the distributive law. -9w + 27 = 8w -8 You have a couple choices here, but I would add 9w to both sides. This cancel with -9w leaving 27 = 17w -8 Add 8 to both sides and then divide both sides by 8 to solve for w. Can you finish from here?

r = litres of red paint w = litres of white paint r + w = 28 r/w = 2/5 so: 5r = 2w which leads to r = (2/5)(w) Replace r in the first equation with the (2/5)(w) that will give you 7/5 w = 28 Can you finish from here?

Multiply (2y+7)(2y+7) It is fine to divide both sides by 3 first, that will make the numbers a little smaller. You will have (2y+7)(2y+7) = 27 After multiplying, you should have 3 terms = 27. Subtract the 27 from both sides so that you will have a trinomial = 0. You can then f...
