I could use alot of help on this please and thankyouuuu

Answer:

B. Step 4 is incorrect , it should be $\frac{10}{8}$

Step-by-step explanation:

6x-1= -2x+9

Step 1

Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1

Step 2: Add like terms on both sides

8x = 10

Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;

$\frac{8x}{8} = \frac{10}{8}$

The two 8s cancel each other and you remain with $x=\frac{10}{8}$
