Question

5d=2e_14 ,, 5e=d+12 in elimination method

Answer 1

Answer:

d=-2,e=2

Step-by-step explanation:

5d+14=2e

d+12=5e

________

4d+2=-3e

e=4d+2/-3

d+12=5(4d+2/-3)

d+12=20d+10/-3

-3d-36 = 20d+10

-20d-3d=10+36

-23d=46

d=-2

substituting d=-2 in one of the two eqautions

-2+12=5e

10=5e

e=2
