Answer:
k=7
Step-by-step explanation:
4+k=11
subtract 4 from both sides to isolate k
k= 7
Answer:
x=38wh + 16
Step-by-step explanation:
multiply both sides of the equation by 2
move the constant to the right
find the final solution
Answer:
x = ± 2
Step-by-step explanation:
Given
x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )
0 = 2x² - 8 ( add 8 to both sides )
8 = 2x² ( divide both sides by 2 )
4 = x² ( take the square root of both sides )
x = ±
= ± 2
y = log5 ( x + 2 )
