3.a. Solve the following equations.

1. Solving we get x=3

2. Solving we get x=-1

Step-by-step explanation:

We need to solve the equations:

1.

Expanding the brackets

Taking LCM on left side we get 12

Add 7/12 on both sides

Adding x/12 on both sides and simplifying

Multiply both sides by 12/3

So, solving we get x=3

2.

Taking LCM and solving:

Cross multiplying

So, solving we get x=-1

its c or d   take a lucky guess my dude
