Answer:
x = 36
Step-by-step explanation:
Remark
This can be done as a proportion. A proportion consists of 2 ratios which means it has 4 parts. If you know three of them, you can solve for the 4th.
We can use the following proportion
42/14 = x / 12 Notice that both ratios have tops and bottoms that use corresponding parts. Cross Multiply
14*x = 42 * 12 Combine the right
14x = 504 Divide by 14
x = 504/14
x = 36

h=19
Answer:
Step-by-step explanation:
Starting with 2x+6=22
You subtract 6 from each side of the equation:
2x=16
You want to isolate the "x" so you divide each side by 2.
x = 8
check your answer: 2x + 6 = 22
2(8) + 6 = 22
16 + 6 = 22
