Question

Solve the following simultaneously equations by elimination method: p-2q=-1,-3p-q=-5

Answer 1

Step-by-step explanation:

so I am solving it by eelimination method hope it helps

1. p-2q=-1.
2. p-2q+1=0. (eq1)

• 3p-q=-5
• 3p-q+5=0 (eq2)

so multiplying eq1 with3

and eq2 with 1

so now:

3p-6q+1 eq 4

3p-q+5 eq 5

so now subtracting eq4 from eq5

you are is q=4/5

now putting 4/5 in eq 1

so p=3/5
