Web15. You need to rearrange the second equation, so x or y is expressed in terms of the other. Then you should be able to substitute this x= or y= expression into where x or y appears in the first equation, then expand (remembering of course that [ (a+b)squared] is the same as (a+b) (a+b)), solve for the single term you have in the first equation ... WebSo I have 2x squareds, and I subtract out a 1/4 x squared, so I'm going to have a 1 and 3/4 x squared. Or you could view this as 8/4 minus 1/4 is 7/4 x squared. 7/4 x squared is equal …

WebSubtract c from both sides: 37 x 2 − 36 x = 7. Multiply both sides by 4 a = 148 from step 1: 5476 x 2 − 5238 x = 1036. Add b 2 = 1296 from step 1 to both sides: 5476 x 2 − 5328 x + … WebINSIDE: 5 × x = 5 x. LAST: 5 × 4 = 20. The next step is to add these together: 2 x 2 + 8 x + 5 x + 20 is the same as 2 x 2 + 13 x + 20. So the original equation (2 x + 5) ( x + 4) = 0 becomes: 2 x 2 + 13 x + 20 = 0. This type of equation is known as a …
WebSolve the simultaneous equations \(x + y = 5\) and \(y = x + 1\) using graphs. To solve this question, first construct a set of axes, making sure there is enough room to plot the two graphs.
