Answer:
x = -5/3
Step-by-step explanation:
start by multiplying the 2 to the (6x-1). you get 12x and -2.
then multiply the 3 and the 5x+1. you get 15x and 3.
now set them equal to each other. 12x - 2= 15x + 3
now subtract 12x from both sides. -2 = 3x + 3
now subtract three from both sides. -5 = 3x
now divide both sides by 3. x = -5/3.
that is how you get the answer.
have a great day!
