How do you solve x + x + x√2=10?
I did x^2 + x^2 + 2x^2 = 100
4x^2 = 100
How do I continue?
I'll be honest, I don't know if you are right in the beginning. I can, however, tell you how to continue from 4x^2=100, if you are right up until that point.
4x^2=100
Divide both sides by 4.
x^2=25
Take the square root of both sides.
x=+-5
14x - 2y = 78
2x - 2y = 6
To continue solving the equation 4x^2 = 100, you need to isolate the variable x. Here's how you can do that:
1. Divide both sides of the equation by 4 to simplify:
(4x^2)/4 = 100/4
x^2 = 25
2. Take the square root of both sides of the equation to solve for x:
√(x^2) = √25
x = ±√25
3. Simplify the square root of 25:
x = ±5
So, the solutions to the equation x + x + x√2 = 10 are x = 5 and x = -5. To check if these solutions are correct, substitute them back into the original equation and see if both sides are equal.
