10x+75-5x=110
You can combine like terms, so add the -5x to the 10x. It becomes 5x.
5x+75=110
The next step is to isolate the variable. To do this, you must first move the 75 to the other side of the equation. You can do that by subtracting it from both sides like so:
5x+75=110
-75 -75
5x=35
The variable isn't isolated yet, though. Now you need to get rid of the 5. You can do that by dividing both sides by 5.
5x=35
/5 /5
x = 7.
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
y=-10x-4
2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4
98 - 3x = 10x + 20, solve for x.subtract 98 from both sides-3x = 10x - 78subtract 10x from both sides-13x = -78multiply both sides by -113 x = 78divide both sides by 13x = 6
10x+7=(-3) 10x=(-10) x=(-1)ans
x=-8
You find x. Oh! There it is!! ^ See?
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
There is no symbol between 7x and 31. Please resubmit using words eg "plus", "equals" etc.
10x=x 9x=0 x=0
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
12x + 9 = 10x + 1 Subtract 10x from both sides: 2x + 9 = 1 Sutract 9 from both sides: 2x = - 8 Divide both sides by 2: x = -4
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
x2 + 10x + 21 = (x + 3)(x + 7)
x + 13x + 10x = 50 - 6
