Answer:

x= -4

Step-by-step explanation:

Simplifying

5x + -4 = 7x + 4

Solving

-4 + 5x = 4 + 7x

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

Add '-7x' to each side of the equation.

-4 + 5x + -7x = 4 + 7x + -7x

Combine like terms: 5x + -7x = -2x

-4 + -2x = 4 + 7x + -7x

Combine like terms: 7x + -7x = 0

-4 + -2x = 4 + 0

-4 + -2x = 4

Add '4' to each side of the equation.

-4 + 4 + -2x = 4 + 4

Combine like terms: -4 + 4 = 0

0 + -2x = 4 + 4

-2x = 4 + 4

Combine like terms: 4 + 4 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Simplifying

x = -4

Your realized income is $2,943.20 /month. How much are your fixed expenses each month? How much could you save per month if you
valkas [14]

Answer:

The saving amount per month is $ 735.8 And

The Expenses amount per month is $2,207.4

Step-by-step explanation:

Given as :

The total per month income = $2,943.20

The saving percentage amount per month = 25% of discretionary money  

So , The saving amount per month = 25 % of $2,943.20

                                                          = .25 × $2,943.20 = $735.8

The amount which is fixed as each month expenses = total monthly income - total monthly saving

So, Expenses amount per month = $2,943.20 - $735.8

                                                       = $2,207.4

Hence The saving amount per month is $ 735.8 And The Expenses amount per month is $2,207.4     Answer
