Answer:

  • -5 39/40 is the answer.

Step-by-step explanation:

  • 2/5(x − 9/10) = −2 3/4
  • => 2x/5 - 18/50 = −2 3/4
  • => 2x/5 - 18/50 = −11/4
  • => 40x/100 - 36/100 = -275/100
  • => 40x/100 = -239/100
  • => 40x = -239
  • => x = -239/40
  • => x = -5 39/40

Conclusion:

Hence, x = -5 39/40 is the answer.

Hoped this helped.
