Presumably this is a simultaneous equation and you have to find the values of x and y. x+3y = 7 x-3y = 1 Add both equations up which will eliminate 3y. 2x+0 = 8 Divide both sides by 2 to find the value of x. x = 4 Substitute 4 for x to find the value of y. x = 4 and y = 1

What is the problem for 4y plus 7-y equals 10 plus 3y?

4y + 7 - y = 10 + 3y My next step is to combine the y's on the left, 3y + 7 = 10 + 3y If I then subtract 3y from both sides I obtain 7 = 10 which is not a true statement. Hence, the equation that you presented is invalid.
