Answer:

- 1/4

Step-by-step explanation:

7a + 2 = 3a + 1

subtract the 1 from both sides

7a + 1 = 3a

subtract 7a from both sides

1 = - 4a

divide by - 4

A = - 1/4

What is the answer for 5x-2x+8=2+6x+6?
Ede4ka [16]

5x - 2x + 8 = 2 + 6x + 6


Add like terms:

5x - 2x = 3x

2 + 6 = 8


3x + 8 = 6x + 8


To isolate the variable, subtract 6x from both sides of the equation:

3x - 6x = -3x


-3x + 8 = 8


Now subtract 8 from both sides:

8 - 8 = 0


-3x = 0


To finish, divide both sides by -3:

0 ÷ -3x = 0


The answer is x = 0


Hope this helps.
