Answer:

x = 3

Step-by-step explanation:

-5(3x -7) + 11 = 1

Distribute 5:

-15x + 35 + 11 = 1

Combine like terms:

-15x + 46 = 1

Subtract by 46 =

-15x = 1 - 46

-15x = -45

Divide by -15:

x = -45 / -15

x = 3

Answer:

x=3

Step-by-step explanation:

Use the distributive property to multiply −5 by 3x−7.

−5(3x−7)+11=1

Add 35 and 11 to get 46.

−15x+35+11=1

Subtract 46 from both sides.

−15x+46=1

Subtract 46 from 1 to get −45.

−15x=1−46

Divide both sides by −15 and you get x=3.
