the first step Andre made was
2x+6=3x-8
or, -x+6=-8
And the first step Diego made was
2x+6=3x-8
or, +6=3x-2x
or, 6=x-8
...
Answer:
10
Step-by-step explanation:
The first equation should be the same with the second one, then we will have an infinite number of solutions of this system.
So if I multiply the first equation by 3, it'll be
6x-18y=3k
So if they should be the same, 30=3k
K=10

Answer:
<h2>x ≥ 2</h2>
Step-by-step explanation:
our expression is defined when x ≥ 1 ,
because , when x ≥ 1
x - 1 ≥ 0
x + 2√(x - 1) ≥ 0
x - 2√(x - 1) ≥ 0
According to case 1 and 2 the solution set for this equality is {x real number where x ≥ 2 }.
