Presumably this is a simultaneous question in which you're asked to find the values of x and y. x+6y = 55 -x+6y = 53 Adding both equations: 0+12y = 108 Divide both sides by 12 to find the value of y: y = 9 Substituting y = 9 into the original equation will enable you to find the value of x: x = 1 and y = 9
4x+6y=62 -6x+6y=-18 what is the ordered pair
You write: --> divide both sides by 6 --> cross out the 6's --> here's y! :) 55 = 6y --> 55/6 = 6y/6 --> 55/6 = y --> 9.16667 = y
16 = 6y +2 Yes
6y + 4.. i think
no
6y
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
it is equal to 6y plus y
3x-6y=-8
Subtracting gives: 10x = 80 so x = 8 and y = 5
but crack
