What value of X will make the following equation true?
14x - 12 = 4 - 42x

The answer to the equation is  

First, you must add 12 on each side

Then, you add 42x on each side

Finally, divide each side by 56

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
