x = 4
9x = 7x + 8. Subtract 7x from both sides. This leaves 2x = 8. Then divide both sides by 2 to get x by itself. So, x = 4.

7x-3 equals 3x plus 8?
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
What is 7x plus 8 equals 10x minus 2?
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
If x equals 6 and y equals 3 then 9x plus 8y equals?
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
9x plus 4 equals x-7?
9x+4 =x-7 8x=-3 x=-3/8
What is 5x plus 32 plus 7x plus 8 equals 180?
5x+32+7x+8=180. By the laws of commutativity we can thus say that 12x+40=180. Subtracting 40 we get 12x=140. Divide by 12 and you get x=(do it yourself) This has nothing to do with calculus by the way.
What is the answer to 9x minus 4 equals 7x plus 8?
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
What is the answer to 9x-8 equals 7x-3?
9x-8=7x-3 9x-7x=-3+8 2x=5 x=5/2 x=2.5
9x plus 8 equals 7x plus 22 x equals?
9x+8=7x+22 To solve for x, combine like terms. (Subtract 7x from both sides, and subtract 8 from both sides. This will give you: 2x=14 Divide both sides by 2. The answer is x=7.
33-2x equals 7x plus 16 what is x?
So 17 = 9x, making x = 1 and 8/9
What are the points of intersection of the curves y equals x2 -7x plus 8 and y equals -x2 plus 9x -6 showing work?
If: y = x2-7x+8 and y = -x2+9x-6 Then: x2-7x+8 = -x2+9x-6 So: 2x2-16x+14 = 0 => x2-8x+7 = 0 Therefore: x = 1 and x = 7 By substitution: x =1, y = 2 and x = 7, y = 8 Points of intersection: (1, 2) and (7, 8)
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
What is the slope of 9y plus 9x plus 7 equals 8 plus 9x?
The slope is 0.
How do you solve 44 equals 9x plus 8?
44 = 9x +8 36=9x 4=x
What is the answer to 5x plus 8 equals 7x?
7x-5x=8 2x=8 x=4
What are the steps for 7x plus 8 equals 36?
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
What is the answer to 7x plus 13x plus 2x plus 8 equals?
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
8 plus 7x equals 20 plus 3x what is x?
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
