Question

I need help finding the value "a" from 3a + 2=a - 6

Answer 1

3a + 2=a - 6
Take away two from both sides of the equal signs
3a = a -8
Take away a from both sides of the equal signs
2a = -8
Divide by two from both sides of the equal sign
a = -4

Answer 2

first subtract a from both sides of the equation:
3a - a + 2 = a - a - 6
2a + 2 = -6
subtract 2 from both sides
2a = - 8
divide both sides by 2:
a = -4
