Step By Step Answer
The equation: -6h + 12 = -36
Lets solve this step by step!
When a variable is right next to a number, for example, -6h, this means the same as 6 · h and 6 × h. This means we will be multiplying. The equation can be represented as -6(h) + 12 = -36. Because we know that negative + negative = positive, we know h cannot be a negative number as the answer is -36. What we can do to solve this is substitute numbers as h to see what can equal -36. -6(8) + 12 = -36, so, this means that h = 8.
Answer:
h = 8
