Best ResponseYou've already chosen the best response.05. A = 6 + E A + E = 32 so we have a set of simultaneous equations, so lets substitute, 6 + E + E = 32 (Putting the first equation into the second) so 6 + 2E = 32 2E = 32  6 2E = 26 so E = 13 Lets put E back into any of the other ones to get A so A = 6 + 13, so A = 19 so emma is 13 and Alex is 19

Best ResponseYou've already chosen the best response.1@sbuck98 #7 M = 2T + 5 M + T = 65 (so M = 65  T) 65  T = 2T + 5 60  T = 2T 60 = 3T T = 20 and M = 45

Best ResponseYou've already chosen the best response.0ohh okay so, Lets assume Alex is A and Emma is E so when we are told that Alex is 6 years older then Emma, we can say that emma (E) + 6 (because we're adding 6 to her age) equals the age of Alex (A), so this makes our statement true, because we are showing that Alex is 6 years older then Emma 5. A = 6 + E Now for the second part of the question we are told, that if you add up Alex's (A) and Emma's (E) ages you get 32, so we know... A + E = 32 so we have a set of simultaneous equations, so lets substitute, ( we can substitute these two equations to get rid of either A or E so that the question can now be solved). If you look at our first equation, its already in the form of A = ....... this is what we want because now we can put this ..... that A equals, into the A of our second equation to get rid of the A component in our second equation all together, so we get... (6 + E {we put 6 + E instead of A}) + E = 32 (Putting the first equation into the second) and now simplify so 6 + 2E = 32 2E = 32  6 2E = 26 so E = 13 Lets put E back into any of the other ones to get A so A = 6 + 13, so A = 19 so emma is 13 and Alex is 19
