{3d−e=7d+e=5 use the linear combination method. the solution is (3, 2). there is no solution. the solution is (2, −1). there are infinitely many solutions.

we are given system of equation as

We are given linear combination method

In linear combination method , we always try to cancel one variable by combining two equations

step-1: Add both equations

-----------------------------------

step-2: Divide both sides by 10

step-3: Solve for e

we can plug d=1

so, solution is (d,e)=(1,-2)..........Answer
