What is a variable divided by the coefficient that will equal 7?
Any variable divided by coefficients can equal 7 - provided the variable can take the appropriate value.
If 3x squared plus 2x equals 7 what does x equal?
You can solve this as a quadratic (it's degree is 2). 9x^2+2x=7 9x^2+2x-7=0 (Hey, a quadratic!) (9x-7)(x+1)=0 Thus, the solutions for x to this problem are -1, and 7/9.
Find the slope -9x-7y equals 8 the slope is?
In order to find the slope of your line, we must first get it into y=mx+b.-9x-7y = 8-9x + 9x - 7y = 8- 7y = 9x + 8-7y/7 = 9x/7 + 8/7-y = 9x/7 + 8/7(-1) -y = 9x/7 + 8/7y = -9x/7 - 8/7The slope is -9/7 and the y-intercept is -8/7
What is 9-x equals 7?
2
What is (9x 7)-(x 3)?
The expression (9x 7)-(x 3) can be simplified as follows: (9x - 7) - (x - 3) = 9x - 7 - x + 3 = 8x - 4
How do you convert 115 inches into 7 equal sections?

9x squared plus 7 x 9x squared -7?
(9x2 + 7)(9x2 - 7) = 81x4 - 49
What is 4 plus 7 plus 9X?
11 + 9X
9x - 16 equals 9x - 23?
x=-7
What is 9x 7y 15 in slope intercept form?
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7
What is 63x over 49 in simplest form?
63x/49 = 9x/7
Solve 2x plus 3 equals 9x equals?
Simplifying 2x + 3 = 9x Reorder the terms: 3 + 2x = 9x Solving 3 + 2x = 9x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9x' to each side of the equation. 3 + 2x + -9x = 9x + -9x Combine like terms: 2x + -9x = -7x 3 + -7x = 9x + -9x Combine like terms: 9x + -9x = 0 3 + -7x = 0 Add '-3' to each side of the equation. 3 + -3 + -7x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -7x = 0 + -3 -7x = 0 + -3 Combine like terms: 0 + -3 = -3 -7x = -3 Divide each side by '-7'. x = 0.4285714286 or x = 3/7 Simplifying x = 0.4285714286 or x = 3/7
