Equation: 7+6•x= 4^2 + (x)^2
Simplify: 13x = 16 + (x)^2
Subtract 16 from both sides:
13x -16 = (x)^2
Divide both sides by x:
13 - 16 = x
Simplify: -3 = x

So the answer would be “3” because when a negative is squared in parentheses, it produces a positive result.

No, it would be -3 because 13 - 16 is -3
