What else can I help you with?
How do you do this problem 7x equals 18 -2x?
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
What is the answer to 9x plus 6 equals 7x plus 18?
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
What is 7x plus 6 equals -18?
7x + 6 = -18 7x = -24 x = -24/7 x = -3.428571 recurring (that is, -3.428571428571...)
6-7x equals 24-21x x equals?
6 - 7x = 24 - 21xSubtract 6 from both sides:- 7x = 18 - 21xAdd 21x to both sides:14x = 18Divide both sides by 14:x = 18/14 = 9/7
7x-3y equals 18 and y equals x-8 what is the value of y?
x=-1.5
What is 6x-7x equals 18?
It is a linear equation in the single variable,x, which is equivalent to x = -18
What is X2 - 7x - 18 equals 0?
x2-7x-18 (x-9) (x+2) x=9 x=-2 X= either 9 or -2
Does 2x plus 18 equals -261-7x?
This is only true if x = -31.
In the equation 3110-7x equals x-66 solve for x?
3110 - 7x = x - 66 <- add -x to both sides 3110 - 8x = -66 <- multiply both sides by -1 8x - 3110 = 66 <- add 3110 to both sides 8x = 3176 <- divide both sides by 8 x = 397
7x plus 8 equals 4x-10?
Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6
X2 plus 7x plus 10 equals?
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
X2plus 7x plus18 equals?
Impossible because the discriminant is less than zero do you mean x2+7x-18? Then if so it is (x+9)(x-2) when factored
