How do you solve for 's' in the equation (r + 8) x 6 = s when r = 12?

Back

Substitute 12 for r: (12 + 8) x 6 = s, which simplifies to 20 x 6 = s, so s = 120.

How do you find 'd' when m = 6 in the equation (m + 6) x 4 = d?

Back

Substitute 6 for m: (6 + 6) x 4 = d, which simplifies to 12 x 4 = d, so d = 48.

Front

How do you solve for 'f' when e = 2 in the equation 12 - (e x 4) = f?

Back

Substitute 2 for e: 12 - (2 x 4) = f, which simplifies to 12 - 8 = f, so f = 4.
