Look at these equations.
9 = 7 + a
a + 8 = b + 5
Use both equations to work out the value of b.

Beginner

11 = 5 + a

11 - 5 = a

6 = a

6 + 4 = b + 3

10 = b + 3

10 - 3 = b

7 = b

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
