98 - 3x = 10x + 20, solve for x.
subtract 98 from both sides
-3x = 10x - 78
subtract 10x from both sides
-13x = -78
multiply both sides by -1
13 x = 78
divide both sides by 13
x = 6

0 equals 800-10x plus 25x2?
If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
What is the x-intercept of the graph of 10x-y20?
-10
4X-12 plus 6X equals 8?
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
If n plus 20 equals 26 then what is n?
Subtract 20 from each side: n= 6. Job done. You could have done that!
X plus 20 plus 10x equals 20 plus 9x x equals?
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
What is x in the problem 2x plus 10x - 4 equals 20?
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
10x plus 20 equals?
Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
What number plus 5 subtract 6 plus equals 20?

What is 12x-3 equals 2x plus 17 algebra?
12x-3=2x+17 10x-3=17 10x=20 x=2
How do you find the value of the discriminant -16x2 plus 10x-20 equals 0?
Calculate 10^2 - 4*(-16)*(-20)
10x-18 equals 5x plus 2?
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
X plus 10 equals 20 what is x?
x+10=20 then you subtract 10 from both sides x=10
What is the answer to -20 equals -4x -6x?
-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2
