6y + 8 = 32 6y + 8 - 8 = 32 - 8 6y = 24 6y/6 = 24/6 y = 4
Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
4x + 6y = 62-6x + 6y = -18 Multiply this equation by -1 the result will be_______________4x + 6y = 626x - 6y = 18_______________ Equation 1 + Equation 2 the result will be10x = 80 ----> X=8Put the value of X in one of the Equations above to find the value of yand so Y=5

4x+6y=62 -6x+6y=-18 what is the ordered pair
6y + 8 = 32 6y + 8 - 8 = 32 - 8 6y = 24 6y/6 = 24/6 y = 4

3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
4x+6y=62 -6x+6y=-18 what is the ordered pair
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
Rearrange the equations in the form of:- 6x-6y = 17-11 -4x+6y = 21 6x-6y = 6 -4x+6y = 21 Add both equatios together in order to eliminate y: 2x = 27 Divide both sides by 2: x = 13.5 Substitute the value of x into the equations to find the value of y: x = 13.5 and y = 12.5
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
