Answer 1

√3x-5=5-20

√3x-5=-15

√3x=-15+5

√3x=-10

Answer 2

It appears you've written an equation involving an irrational expression. Let's solve it step by step:

√(3x) - 5 = 5 - 20

To start solving, let's isolate the square root term on one side of the equation:

√(3x) = 5 - 20 + 5

Simplify the right side:

√(3x) = -10

Next, square both sides to eliminate the square root:

(√(3x))^2 = (-10)^2

3x = 100

Finally, isolate x by dividing both sides by 3:

x = 100 / 3

So the value of x in the equation √(3x) - 5 = 5 - 20 is x = 100/3. However, it's important to note that this solution does not satisfy the original equation since the square root of a negative number is undefined in the real number system. Thus, the initial equation is not valid.
