Answer:

no \: solution

Step-by-step explanation:

1) Expand.

7a + 5a + 15 = 8a + 4a+ 8

2) Simplify 7a + 5a + 15 to 12a + 15.

12a + 15 = 8a + 4a+ 8

3) Simplify 8a + 4a + 8 to 12a + 8.

12a + 15 = 12a + 8

4) Cancle 12a from both sides.

15 = 8

5) Since 15 = 8 is false, there's no solution.

no \: solution

Therefor, this equation has no solution.

Membership to two different clubs are represented by the equations below. The x-value represents the number of months dues are p
mestny [16]

It would take 2 months for the membership of both clubs to be the same

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

The standard form of a linear equation is:

y = mx + b

Where m is the rate of change and b is the y intercept

Let y represent the total cost of dues over x months, hence given that:

y = 3x - 5     (1)

Also:

4x - 3y = 5

y = (4x - 5)/3      (2)

For the membership of both clubs to be the same:

3x - 5 = (4x - 5)/3    

9x - 15 = 4x - 5

x = 2

It would take 2 months for the membership of both clubs to be the same
