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

3y plus 7 makes a tomato pie and 1-y is .....em.......oh look at that it is past my bedtime! Cheerio!
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
X equals 1 and so does Y
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
