Question

In 4x + 19 = 3x - 1 the value of x is​

Answer 1

Answer:

x = -20

Explanation:

As per the information provided in the question, We have :

4x + 19 is equal to 3x - 1.

We are asked to find the value of x. In order to find the value of x, We will use transposing method.

Thus,

⇏ 4x + 19 = 3x - 1

Transposing 3x to left side and +19 to the right side,

⇏4x - 3x = -1 - 19

performing subtraction in left hand side,

⇏1x = -1 - 19

performing subtraction in right hand side,

⇏1x = -20

⇏x = -20/1

⇏x = -20

∴ Value of x is -20
