Vera_Pavlovna [14]

Answer:

A) T = -1.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10t+4−2t=2−2(t+4)

10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)

10t+4+−2t=2+−2t+−8

(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)

8t+4=−2t+−6

8t+4=−2t−6

Step 2: Add 2t to both sides.

8t+4+2t=−2t−6+2t

10t+4=−6

Step 3: Subtract 4 from both sides.

10t+4−4=−6−4

10t=−10

Step 4: Divide both sides by 10.

Hope this helps!
