Question

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

Answer 1

Hi,

Equation;

$n = 8 \\ \frac{1}{2} m - \frac{3}{4} n = 16$

Variable n is given so no need to write it down. Instead use 8.

Solving:

$\frac{1}{2} m - \frac{3}{4} 8 = 16 \\ \frac{1}{2} m - 3 \times 2 = 16 \\ \frac{1}{2} m - 6 = 16 \: \: \: | \times 2 \\ m - 12 = 32 \\ m = 32 + 12 \\ \\ m = 44 \: \: \: \: \: \: \: (result)$

Hope this helps.

Answer 2

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

since n = 8 we can substitute this value into the equation​.

1/2m - 3*8/4 = 16​

1/2m - 24/4 = 16​

1/2m - 6 = 16​

1/2m = 16 + 6 = 22​

1/2m = 22/1​

1*1 = 2m*22 = 44m​

m = 1/44​

Answer m = 1/44

​Hope this helps!​​​​
