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

Step-by-step explanation:
l*w*h
A) C + A = 630
B) 2C + 5A = 2,910 Multiplying A by -2
A) -2C -2A = -1,260 Then adding it to B
B) 2C + 5A = 2,910
3A = 1,650
A = 550
A) C + 550 = 630
