please answer me fast

Answer 1

Answer:

3.5x + -9 = 2.4x + 13

Reorder the terms:

-9 + 3.5x = 2.4x + 13

Reorder the terms:

-9 + 3.5x = 13 + 2.4x

Solving

-9 + 3.5x = 13 + 2.4x

Solving for variable 'x'.

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

Add '-2.4x' to each side of the equation.

-9 + 3.5x + -2.4x = 13 + 2.4x + -2.4x

Combine like terms: 3.5x + -2.4x = 1.1x

-9 + 1.1x = 13 + 2.4x + -2.4x

Combine like terms: 2.4x + -2.4x = 0.0

-9 + 1.1x = 13 + 0.0

-9 + 1.1x = 13

Add '9' to each side of the equation.

-9 + 9 + 1.1x = 13 + 9

Combine like terms: -9 + 9 = 0

0 + 1.1x = 13 + 9

1.1x = 13 + 9

Combine like terms: 13 + 9 = 22

1.1x = 22

Divide each side by '1.1'.

x = 20

Simplifying

x = 20

Answer 2

Step-by-step explanation:

3.5x-2.4x=13+9

1.1x=24

11/10(x)=24

x=240/11

x=2.11
