Question

write the working rule of solving 2 or 3 linear equation​

Answer 1

Step-by-step explanation:

To solve a linear equation, firstly you should make one of the two coefficients equal. After making them equal, add or subtract them (Depends on the signs!). By doing this, you eliminate one term and find the value of another. Then simply substitute the answer in either of 2 equations to find the value of the other term.

I hope this helps you.
