Identify the operation you should use when eliminating these simultaneous equations: (1)(1)2𝑓−3𝑒2f−3e==44 (2)(2)𝑓+3𝑒f+3e==2020

Question

Identify the operation you should use when eliminating these simultaneous equations:

  1. 2f3e=44 2f - 3e = 44
  2. f+3e=20 f + 3e = 20

Solution

To eliminate these simultaneous equations, you should use the operation of addition. Here are the steps:

  1. Write down the two equations:

    2f - 3e = 4 ...(1)

    f + 3e = 20 ...(2)

  2. Add equation (1) and equation (2) together. The '3e' in equation (1) and '-3e' in equation (2) will cancel each other out:

    (2f - 3e) + (f + 3e) = 4 + 20

  3. Simplify the equation:

    3f = 24

  4. Solve for 'f':

    f = 24 / 3 = 8

  5. Substitute 'f = 8' into equation (2) to solve for 'e':

    8 + 3e = 20

  6. Solve for 'e':

    3e = 20 - 8 = 12

    e = 12 / 3 = 4

So, the solution to the simultaneous equations is f = 8 and e = 4.
