Answer:

See below

Step-by-step explanation:

The solution choices all agree that x = 1±√2. The second equation tells you ...

y = ±2√(x+2)

so the sign of the √2 term in x is the same as the sign of the √2 term in y. The answer choices circled in red are the ones that meet this requirement.

What is 2x-6 = 3x+1-X-7 and you have to regroup/ divide by number next to x?

Elena L [17]

Answer:

infinite solutions

Step-by-step explanation:

2x-6 = 3x+1-X-7

Combine like terms

2x-6 = 3x-x +1-7

2x-6 = 2x -6

subtract 2x from each side

-6 = -6

Since this is a true statement, x can be any real number
