Solve the equation:
4y2 + 7 = 19
(write your answer in exact form)

y2=3

Step-by-step explanation:

4y2+7=19

Subtract 7 from both sides.

4y  2 =19−7

Subtract 7 from 19 to get 12.

4y2=12

Divide both sides by 4.

y2= 12/4

Divide 12 by 4 to get 3.

y2=3

4y2 + 7 = 19

Step-by-step explanation:

4y2 =19-7

4y2=12

4yx2=12

8y=12

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
