2x plus 4x plus 7x equals?
13x
6x plus 10 plus 7x equals -146?
13x = -156 so x = -12
7x plus 6x-1 equals 0?
7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
What are the solutions of the equation 6x plus 7x-8 equals -5?
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
2x plus 4x plus 7x equals?
13x
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.
6x plus 10 plus 7x equals -146?
13x = -156 so x = -12
7x plus 6x-1 equals 0?
7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
What are the solutions of the equation 6x plus 7x-8 equals -5?
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
X^2-7x+12?
13x
How can you Solve this problem by substitution 6X- Y equals -9 4 plus 7X equals -Y?
We have two equations.6x-y=-9 and -y=7x+4.We substitue 7x+4 into the first equation and we have6x+7x+4=-9 or 13x=-13 so x=-13/13 of -1Now plug that into either equation and we have-y=-7+4 or -y=-3 so y=3.The solution is (-1,3)
How do i Solve 7x equals 20 plus 20x?
7x=20+20x collect terms containg x on one side and then factorize -13x=20 0r, x=-20/13
What is the answer to 7x plus 2 equals 158-6x?
7x + 2 = 158 - 6x7x + 2 + 6x = 158 - 6x + 6x13x + 2 - 2= 158 - 213x / 13 = 156/13x = 12
If 7x equals 42 what is value of x?
6
How do you do this problem 7x equals 18 -2x?
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
