Mathematics
1 answer:
julsineya [31]3 years ago

Answer:

a. Step 1

Step-by-step explanation:

When solving equations, in order to isolate the variable (get the 'x' by itselt), you need to use inverse (opposite) operations.  In the equation:

l2x - 4l - 3 = 3

Step 1: l2x - 4l = -3 + 3 *this step is incorrect because the inverse of subtraction is addition so the '-3' should be added to both sides:

l2x - 4l - 3 + 3 = 3+ 3

Step 2: l2x - 4l = 6

Step 3: 2x - 4 = 6

Step 4: 2x  = 10

Step 5: x = 5
