Answer:
x = 
Step-by-step explanation:
12y = 75 + 5x + 2x - 1
combine like terms:
12y = 74 + 7x
subtract 74 from both sides:
7x = 12y - 74
divide both sides by 7:
x = 
2 + 3x = 17
2 + 3(5) = 17
2+ 15 = 17

Answer:

Step-by-step explanation:

basically we want to get rid of the √3 on the denominator
to do so we multiply it by itself so it is a perfect square
