Explanation:

Step1: Isolate B, divide by 10

$B = \frac{20}{10} = 2$

Step2: Isolate C, divide by 4

$C = \frac{36}{4} = 9$

Step3: Calculate division for E

$E = 49 \div 7 = 7$

Step4: Calculate multiplication for F

$F = 5 \times 6 = 30$

Step5: Calculate division for G

$G = 63 \div 7 = 9$

Step6: Calculate division for H

$H = 5 \div 1 = 5$

Step7: Isolate J, rearrange formula

$J = \frac{48}{6} = 8$

Step8: Isolate K, rearrange formula

$K = \frac{8}{4} = 2$

Step9: Isolate L, rearrange formula

$L = \frac{9}{9} = 1$

Step10: Isolate M, rearrange formula

$M = \frac{5}{5} = 1$

Step11: Isolate N, divide by 2

$N = \frac{2}{2} = 1$

Step12: Calculate multiplication for P

$P = 8 \times 6 = 48$

Step13: Isolate Q, divide by 5

$Q = \frac{35}{5} = 7$

Step14: Isolate R, divide by 8

$R = \frac{16}{8} = 2$

Step15: Calculate multiplication for S

$S = 8 \times 3 = 24$

Step16: Isolate T, multiply by 4

$T = 1 \times 4 = 4$

Step17: Isolate U, multiply by 10

$U = 3 \times 10 = 30$

Step18: Isolate V, multiply by 1

$V = 8 \times 1 = 8$

Step19: Calculate division for W

$W = 7 \div 7 = 1$

Step20: Calculate multiplication for Y

$Y = 9 \times 3 = 27$
