You need to perform the multiplication to the right side, such that:

`144 = 2*7*h + 2*5*h`

`144 = 14h + 10h`

Performing the sum of the terms that contain the unknown h, yields:

`144 = 24h`

You need to evaluate h, hence, you need to divide by 24, such that:

`h = 144/24 => h = 6`

**Hence, evaluating the value of `h, ` under the given conditions, yields `h = 6` .**

We have to find h given 144 = 2h(7+5)

144 = 2h(7+5)

Simplify the terms within the brackets on the right hand side

144 = 2*h*12

Simplify the expression on the right hand side

144 = 24*h

Divide both the sides by 24

144/24 = (24*h)/24

6 = h

The solution of the equation is h = 6.
