Y = 82x, the value of Y will be 82 times whatever value of x that is chosen
Solving 11x-28=82x for x involves the following: -28=82x-11x -28=71x -28/71=x x=.3943 (truncated to 4 decimal places)
2x + 1 = 82x = 7x = 7/2 = 3.5whew !
x + 36 = 82x = 82 - 36x = 46
If that's -82x + 99, the answer is (3x - 11)(5x - 9) If that's +82x + 99, the answer is (3x + 11)(5x + 9)
(2x - 1) + (2x + 1) = 324x = 32x = 82x-1 = 152x+1 = 17

2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
2x+4=82x=8-4 (you subtract 4 on both sides)2x=4 (you then divide by 2 on both sides)x=2
-82X, and you're missing an operator there.
2 ( x + 4 ) = 92x + 8 = 92x = 9 - 82x = 1x = 1 / 2x = 0.5
-2x+8=3y(-2x+8)/3=yplug in values of x or y into equation to find x or yTo obtain specific values for x or y, you would need 2 equations for the two variables. You can still solve the equation for a specific variable, in terms of the other. For example, to solve for x:2x + 3y = 82x = 8 - 3yx = (8 - 3y) / 2
