Question

Solve the following equation by elimination method: 0.5 R1 + 1.2 R2 = 1.486; 4.5 R1 – 2 R2 = 4.67​

Answer 1

Answer:

(0.5 R1 +1.2 R2 = 1.486) whole multiplied by 9 to get ( 4.5 R1 + 10.8 R2 = 13.374) then subtract 4.5 R1 - 2 R2 = 4.670

After doing the required calculations

You get R1 = 1.66 (approx.)

and R2 = 4.511
