Find the values of X and Y from the simultaneous equations: 1) 2x + 5y = 33 2) x + 3y = 19
2x + 5y = 33 2) x + 3y = 19 multiply equation 2 by a factor of 2 giving you 2x + 6y = 38 Your two equation are now: 1) 2x + 5y = 33 3) 2x + 6y = 38 Subtract 3 from 1 to eliminate the x's Giving you Y = 5 Now, as you know Y = 5 replace Y in either of the original equations to get your vaule for X. Here we will choose equation 2 If Y = 5 X + 3(5) = 19X = 19 - 15 X = 4
