​

Answer 1

Answer:

√x + x = 6

Step-by-step explanation:

√x - 3 + x = 3

√x + x = 3 + 3

√x + x = 6

Answer 2

1. Step-by-step explanation:

So the answer

x=4

$\sqrt{x} + x = 3 + 3 \\ \sqrt{x} + x = 6 \\ squaring \: on \: both \: sides \\ x + x {}^{2} = 36 \\x {}^{2} + x - 36 = 0 \\ 4 { }^{2} + 4 - 36 = 0 \\ so \: x = 4$
