Answer:

t = 11.

Step-by-step explanation:

7 -1(5t - 13) = -25.

Distribute the -1.

7 - 5t + 13 = -25

Combine like terms.

20 - 5t = -25

Subtract 20 from both sides.

-5t = -55

Divide by -5.

t = 11.

Answer:

t = 9

7 - 1 (5t - 13)= -25

7 -5t +13 = -25

-5t + 20 = -25

-20 -20

-5t = -45

divide -5 from both sides of the equal sign

t = 9

FromTheMoon [43]

Answer:

x = 8.45

Step-by-step explanation:

5.4 + 0.2x = 7.09

Subtract 5.4 from both sides to leave 0.2x alone

0.2x = 1.69

Divide by 0.2 on both sides to isolate x

x = 1.69/0.2

x = 8.45
