-8x plus 7 equals -7x-2?
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
What is x is 7x 49?
If you mean: 7x = 49 then the value of x is 7
Is x7 the same as 7x?
x7 is the same as 7x. However, x^7 is significantly different from 7x
How do you solve 3x equals 7-4x?
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
How do you do 7x plus 3 equals 10?
7x+3=10 7x=7 {subtract 3 from each side} x=1 {divide each side by 7}
Is 1x plus 13 the greatest common monomial factor of 7x 91?
If you mean: 7x+91 then it can be factored to 7(x+13)
How do you solve 7x - 5 equals -13 plus 56?
7x - 5 = -13 + 56Perform the indicated addition on the right side of the equation:7x - 5 = 43Add 5 to each side:7x = 48Divide each side by 7 :x = 48/7 = 6 6/7
How is ln7x equal to ln13?
Solving ln(7x) = ln(13) for x is really easy.First, exponentiate both sides of the equation with the mathematical constant, e (2.71828):eln(7x) = eln(13), which reduces to 7x = 13.Now, divide both sides of the equation by 7:(7/7)x = 13/7.This gives us the answer x = 13/7, or 1.857.You may have noticed that the exponentiating step was just a formality as the terms inside of the ln brackets had to be equal, so we could have simply started at 7x = 13.
6x² plus 7x equals 5?
6x2 + 7x = 56x2 + 7x - 5 = 0x =[ -7 ± √[72 - 4(6)(-5)] ]/2(6)x = [-7 ± √(49 + 120)]/12x = (-7 ± √ 169)/12x = (-7 ± 13)/12x = (-7 + 13)/12 or x = (-7 - 13)/12x = 6/12 = 1/2 orx = -20/12 = - 5/3
How do you solve this using substitution method 7x-4y equals 13 3x-y equals 7?
7x-4y= 13 3x-y= 7 we have two equations we need to find the y, because it is by him self. and now for finding the y we transpose -y eqaul to 7 -3x then subt to equation 1 7x-4(7-3x)= 13 7x -28 + 12x= 13 combine like terme 7x +12x -28 =13 19x -28 = 13 +28 +28 19x= 41 19x/19 = 41/19 x= 2.15 now find the y 7(2.15) - 4y= 13 15.0.5 -4y = 13 -15.05 -15.05 -4y=-2.05 -4y /-4 y=-0.5125 the solution is ( 2.15, 0.5125)
How do you find the value of X in this problem X-7 equals -13?

What are the steps for 7x plus 29 equals 36?
7x + 29 = 36 7x + 29 - 29 = 36 - 29 7x = 7 7x/7 = 7/7 x = 1
What is -6x plus 2 equals 7x plus 9?
x=-7/13
What properties of equality allows 7x - 1 to equal 7x - 7?
None. 7x - 1 is not equal to 7x - 7.
How do you factor 7X plus 7?
7x + 7 = 7(x + 1)
What is the soultion to 4x-13 equals 22-3x?
4x - 13 = 22 - 3x add 3x to both sides 7x - 13 = 22 add 13 to both sides 7x = 35 divide both sides by 7 x = 5
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
