Answer 1

Answer:

hope it will help you!

Step-by-step explanation:

Simplifying

0.4(x + -0.45) = 9.2

Reorder the terms:

0.4(-0.45 + x) = 9.2

(-0.45 * 0.4 + x * 0.4) = 9.2

(-0.18 + 0.4x) = 9.2

Solving

-0.18 + 0.4x = 9.2

Solving for variable 'x'.

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

Add '0.18' to each side of the equation.

-0.18 + 0.18 + 0.4x = 9.2 + 0.18

Combine like terms: -0.18 + 0.18 = 0.00

0.00 + 0.4x = 9.2 + 0.18

0.4x = 9.2 + 0.18

Combine like terms: 9.2 + 0.18 = 9.38

0.4x = 9.38

Divide each side by '0.4'.

x = 23.45

Simplifying

x = 23.45
