There are two approaches to solving the equation -3x + 10 = 4x - 20

Subtract 4x from both sides. OR Add 3x to both sides.

–7x + 10 = –20 OR 10 = 7x – 20

Solve the equation using both approaches.

What is the solution?

a. x = -30/7
b. x = -7/30
c. x = 30/7
d. x = 7/30

Answer:

c

Step-by-step explanation:

using the 10 = 7x - 20 for simplicity.

10 = 7x - 20      add 20 to both sides

30 = 7x             divide both sides by 7

30/7 = x
Pretty sure it’s C but let me know if I’m wrong !
