1. solve 10x + 4 = 39

2. solve 4(9x + 2)= 152

10x + 4 = 39

10x = 35
x = ?

4(9x + 2)= 152
36x + 8 = 152
36x = 144
x = ?

1. To solve the equation 10x + 4 = 39, we need to isolate the variable x.

First, let's get rid of the constant term on the left side of the equation. We can do this by subtracting 4 from both sides of the equation:

10x + 4 - 4 = 39 - 4

This simplifies to:

10x = 35

Now, we need to isolate x by getting rid of the coefficient 10. We can do this by dividing both sides of the equation by 10:

10x/10 = 35/10

Simplifying further:

x = 3.5

Therefore, the solution to the equation 10x + 4 = 39 is x = 3.5.

2. To solve the equation 4(9x + 2) = 152, we need to isolate the variable x.

First, let's distribute the 4 on the left side of the equation:

36x + 8 = 152

Next, let's isolate x by subtracting 8 from both sides of the equation:

36x + 8 - 8 = 152 - 8

Simplifying further:

36x = 144

Now, to isolate x, we need to divide both sides of the equation by 36:

36x/36 = 144/36

Simplifying further:

x = 4

Therefore, the solution to the equation 4(9x + 2) = 152 is x = 4.
