Answer 3

It seems like you've provided two equations with variables. Let's solve them step by step:

Equation 1: 5x - 5 = 2x - 7

First, let's isolate the variable x on one side of the equation:

Subtract 2x from both sides: 5x - 2x - 5 = -7

Simplify: 3x - 5 = -7

Now, add 5 to both sides to isolate 3x: 3x - 5 + 5 = -7 + 5

Simplify: 3x = -2

Finally, divide both sides by 3 to solve for x: x = -2 / 3

Equation 2: 11x - 1.8 = 7x + 1.4

First, let's isolate the variable x on one side of the equation:

Subtract 7x from both sides: 11x - 7x - 1.8 = 1.4

Simplify: 4x - 1.8 = 1.4

Now, add 1.8 to both sides to isolate 4x: 4x - 1.8 + 1.8 = 1.4 + 1.8

Simplify: 4x = 3.2

Finally, divide both sides by 4 to solve for x: x = 3.2 / 4 x = 0.8

So, the solutions for the given equations are:

1. x = -2 / 3
2. x = 0.8
