Question

When solving an equation like 2x + 10 = 2(x + 5), and, when simplified, you get x = x, 10 = 10, or 0 = 0, what is the solution for x?

Answer 2

it means there is infinite solutions....no matter what number you sub in for x, it will still equal.

example :
2x + 10 = 2(x + 5)......lets say x = 1
2(1) + 10 = 2(1 + 5)
2 + 10 = 2(6)
12 = 12 (correct)

2x + 10 = 2(x + 5).....lets say x = 2
2(2) + 10 = 2(2 + 5)
4 + 10 = 2(7)
14 = 14 (correct)

no matter what number you sub in for x, it will always equal

Answer 3

ok thanxs

Answer 4

the solution is all real numbers
if you had to write it down, you might write it this way
\[ - \infty < x < \infty \]
