Answer 3

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

1) 5x - 2 = x - 18

To solve for x, we'll start by isolating the x terms on one side of the equation and the constant terms on the other side.

Subtract x from both sides: 4x - 2 = -18

Next, add 2 to both sides: 4x = -16

Finally, divide both sides by 4: x = -4

So the solution to this equation is x = -4.

2) 18 - 7x = 6 - 4x

Let's simplify the equation by combining like terms:

Move -7x and -4x to one side: 18 + 4x - 7x = 6

Combine the x terms: 18 - 3x = 6

Next, subtract 18 from both sides: -3x = 6 - 18 -3x = -12

Finally, divide both sides by -3: x = -12 / -3 x = 4

So the solution to this equation is x = 4.

3) 2x + 13 = 5x + 19

Similar to the previous equations, let's isolate the x terms and constant terms:

Subtract 2x from both sides: 13 = 3x + 19

Next, subtract 19 from both sides: -6 = 3x

Finally, divide both sides by 3: x = -6 / 3 x = -2

So the solution to this equation is x = -2.

4) 2x = 18 - x

To solve for x, let's isolate the x terms on one side and the constant terms on the other side:

Add x to both sides: 2x + x = 18

Combine the x terms: 3x = 18

Finally, divide both sides by 3: x = 18 / 3 x = 6

So the solution to this equation is x = 6.

5) 7x + 3 = 30 - 2x

Let's simplify the equation by combining like terms:

Move -2x to the left side: 7x + 2x = 30 - 3

Combine the x terms: 9x = 27

Finally, divide both sides by 9: x = 27 / 9 x = 3

So the solution to this equation is x = 3.

To summarize, the solutions to the given equations are:

1) x = -4 2) x = 4 3) x = -2 4) x = 6 5) x = 3

These are the values of x that satisfy each equation.
