Solve the following equation for the unknown variable: H/4 + 7.8 = 12.4

Answer 1

To solve the equation (H/4) + 7.8 = 12.4, we need to isolate the variable H on one side of the equation.

First, let's subtract 7.8 from both sides of the equation:
(H/4) + 7.8 - 7.8 = 12.4 - 7.8
(H/4) = 4.6

Next, to eliminate the fraction, let's multiply both sides of the equation by 4:
4 * (H/4) = 4.6 * 4
H = 18.4

Therefore, the solution is H = 18.4.
