Y+23=59 solve for y i dont know if i have to add or subtract the 23 and 59

neonofarm [45]

When you move a number to the opposite side of the equation, in this occasion it will be 23- it changes to the opposite value. So us 23 is a positive value you can move it and change it to a negative. Or in other words suntract -23 from all sides of the equation, which will be equal to:
y = 59 - 23
Y = 36

What is the solution to the equation? √2x+10−6=2 *Picture of the Problem Below*

Klio2033 [76]

Answer:

x = 27

Step-by-step explanation:

Given

$\sqrt{2x+10}$ - 6 = 2 ( add 6 to both sides )

$\sqrt{2x+10}$ = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
