In electrolysis, positive ions will be attracted to the negative cathode (the cathode being negative can be remembered because cats are evil). However, in aqueous solutions there are 2 positive ion...

We first expand the first set of brackets by multiplying each element of it by the second set of brackets so (x + 1)(2x + 3) = (x)(2x + 3) + (1)(2x + 3) = x(2x + 3) + (2x + 3). We can then expand out the ...

x=4, y=-2

"Photo" means light and "synthesis" means to make something. Photosynthesis is the production of oxygen and glucose from sunlight, carbon dioxide and water in green plants. The glucose...

Using the elimination technique:As we have -2y in both equations we can take the equations away from each other in order to eliminate -2y and create a new linear equation involving only x. this equation w...
