Question

solve the following equation 3x-4=4x-16​

Answer 1

Answer:

x = 2.857142857

Step-by-step explanation:

Simplifying

3x + -4 + 4x = 16

Reorder the terms:

-4 + 3x + 4x = 16

Combine like terms: 3x + 4x = 7x

-4 + 7x = 16

Solving

-4 + 7x = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 7x = 16 + 4

Combine like terms: -4 + 4 = 0

0 + 7x = 16 + 4

7x = 16 + 4

Combine like terms: 16 + 4 = 20

7x = 20

Divide each side by '7'.

x = 2.857142857

Simplifying

x = 2.857142857
