Question

For what value of ‘p’, is the L.H.S. equal to R.H.S. for the equation, 4p – 12= 4?

• A. 2
• B. 4
• C. 5
• D. 3

Answer 1

The correct option is B 4

Equation: 4p – 12 = 4

For p = 5, L.H.S. = 4 × 5 – 12 = 20 – 12 = 8 ≠ 4 (R.H.S.)

For p = 2, L.H.S. = 4 × 2 – 12 = 8 – 12 = -4 ≠ 4 (R.H.S.)

For p = 4, L.H.S. = 4 × 4 – 12 = 16 – 12 = 4 = 4 (R.H.S.)

For p = 3, L.H.S. = 4 × 3 – 12 = 12 – 12 = 0 ≠ 4 (R.H.S.)
