Answer 3

To solve the given equations, let's work through each one step by step:

1. 2x - 15 = 13

First, we isolate the variable term by adding 15 to both sides of the equation:

2x - 15 + 15 = 13 + 15

Simplifying:

2x = 28

Next, we divide both sides of the equation by 2 to solve for x:

2x/2 = 28/2

Simplifying:

x = 14

Therefore, the solution to the equation is x = 14.

2. 130 - 4x = 70

Similar to the previous equation, we'll start by isolating the variable term. This time, we'll subtract 130 from both sides of the equation:

130 - 4x - 130 = 70 - 130

Simplifying:

-4x = -60

Next, we divide both sides of the equation by -4 to solve for x:

-4x/-4 = -60/-4

Simplifying:

x = 15

Therefore, the solution to the equation is x = 15.

To summarize the solutions:

1. The solution to the equation 2x - 15 = 13 is x = 14.
2. The solution to the equation 130 - 4x = 70 is x = 15.
