To solve for "j" in the equation 8j - 18 = 14, you can isolate the variable by adding 18 to both sides of the equation. This will give you 8j = 32. Then, divide both sides of the equation by 8 to find that j = 4.

If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
(42) + 2 = 18
x-9=9 When you add 9 to both sides, you are left with x=18.
x+5=18 When you move 5 to the other side, you get x=13.
it is 3x3 not that hard

plot the equation 3x2+9x-6y+18=0 of the parabola.
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
The equation is: 18N+2 = 19N
By taking away, from the left side, anything that isn't "x". In this case, subtract 18 from both sides.
