2x+a=p 2x=p-a x=.5p-.5a
2x2-y2
x = -8
2x+3 = 7 2x = 7-3 2x = 4 x = 2
If: 2x = -2 Then: x = -1 by dividing both sides by 2
2x+a=p 2x=p-a x=.5p-.5a
You can't solve a formula with no equals sign
2x2-y2
y= -2x
2x-3=9 so 2x=12 and x=6
3
x = -8
meant to be e^x = 2e^1-2x
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
2x+32 = 1 2x = 1-32 2x = -31 x = -15.5
2x+3 = 7 2x = 7-3 2x = 4 x = 2
get it to y= -2y = 1 - 2x y = x - 0.5
