⑦⑦7) solue each of the following pairs of linear equation cross multiplication method: ④5x-64 +30=0 5x+4y-2020 37-4y+600 3x+9-9-0​

Answer :

Answer:

To solve pairs of linear equations using the cross multiplication method, we first need to rewrite the given equations in the standard form a++=0. Then, we apply the cross multiplication formula. Let’s solve each pair step-by-step:

1. Solving the Pair:

5x−6y+30=0

5x+4y−2020=0

Step 1: Standard Form

Both equations are already in the standard form:

5x−6y+30=0     (1)

5x+4y−2020=0     (2)

Step 2: Applying Cross Multiplication

The cross multiplication method involves:
