Question

|3 + y| - 4 = 7 solve

Answer 1

y = 8 or y = -14

Answer 2

y = 8 or y = -14

Explanation:

Solve for y over the real numbers:

abs(y + 3) - 4 = 7

Add 4 to both sides:

abs(y + 3) = 11

Split the equation into two possible cases:

y + 3 = 11 or y + 3 = -11

Subtract 3 from both sides:

y = 8 or y + 3 = -11

Subtract 3 from both sides:

Answer: y = 8 or y = -14
