3x + 2y =4 and 4x - 17 = 5y. Solve the simultaneous equations.
- write out each equation one underneath the other so that the x’s are in one column and the y’s are in another.2) we also need to make sure that the numbers are also aligned up3) for 4x - 17 = 5y, we can add 17 to both sides of the equation. That leaves us with 4x = 5y + 17.4) now, we need to minus 5y from both sides. That leaves us with 4x - 5y =175) we need to get either of the coefficients (numbers in front of the x and y) the same in both equations. for example, we can choose to make both the x’s the same. To do that, we can multiply (3x + 2y = 4) by 4 and (4x - 17 = 5y) by 3.that gives us 12x
