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.
There are a lot of two step equations that could give you 18 like: 48x - 250= 614 15x - 17= 253 31x + 28= 586 6x + 59 = 167
it is 3x3 not that hard
By taking away, from the left side, anything that isn't "x". In this case, subtract 18 from both sides.
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.
A two-step equation with a variable that equals 23 could be (2x + 5 = 23). To solve for (x), first subtract 5 from both sides to get (2x = 18), and then divide by 2 to find (x = 9). Thus, the solution satisfies the original equation.
First, you want to get the y on one side of the equation and everything else on the other side. To do this, add 3x to each side: 9y = 3x + 18 The next step is to divide both sides by 9, which gives you the equation solved for y: y = x/3 + 2
multiply each side by 18 so that the denominator of 18 cancels and -6X18=b therefore b=-108
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.
2(9+x)>2(4+x) 18+2x>8+2x -2x -2x 18>8 no solution
a + 18 = 90 is a linear equation in one variable. Adding both sides by -18, we get a + 18 - 18 = 90 - 18 a = 90 - 18 = 72
