To keep it balanced, whatever you do to one side of the equals, do to the other:

2d + 7 = 9

⇒ 2d + 7 - 7 = 9 - 7

⇒ 2d = 2

⇒ 2d ÷ 2 = 2 ÷ 2

⇒ d = 1

4(9)-11=25 2(9)+7=25 d=9

Y+7=9 equals 2+7=9.

The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.

144 9+7 = 16 and 9*16 = 144

It is: -2+9 = 7
