Question

What is the value of m in the equation 1/2m - 3/4n = 16, when n = 8?

Answer 1

Answer: m= 44

Explanation:

1/2m - 3/4n = 16 when n is 8 put it into the equation and solve for m.

1/2m - 3/4(8) = 16

1/2m - 6 = 16

+6 +6

1/2m = 22

m = 44

Answer 2

44

Explanation:

● (1/2 )× m - (3/4) × n = 16

Replace n by 8 and the fraction by decimal numbers (1/2 = 0.4 and 3/4 =0.75)

● 0.5 × m - 0.75 × 8 = 16

● 0.5m - 6 = 16

Add 6 to both sides

● 0.5 m - 6 + 6 = 16+ 6

● 0.5 m = 22

Multiply both sides by 2

● 0.5m × 2 = 22 × 2

● m = 44
