We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.

Step-by-step explanation:
Vertical angles are equal so we can set 47 = 3x + 2

47 = 3x + 2
Subtract 2 from each side
45 = 3x
Divide both sides by 3
15 = x
