What is the solution to the equation? 1../ 13.5 + 5x = 20

what is the solution to the equation? 2..//-14x + 16 = -12

solve for x.
-32x – 18 = -2

solve for x.
4 + x/5 = -3

Step-by-step explanation:

1. For the equation , subtract 13.5 from both sides of the equation:

And divide both sides by 5:

2. For the equation , subtract 16 from both sides of the equation:

And divide both sides by -14:

3. For the equation , add 18 to both sides of the equation:

And divide both sides by -32:

4. For the equation   subtract 4 from both sides of the equation:

And multiply both sides by 5:

The answers are:

1

2

To know the solution of the problems, we need to isolate each variable.

Remember that:

- If we have an equality: if the number is adding (positive sign), and if you need to move it to the other side of the equality, its sign changes to negative.

- If we have an equality: if the number is subtracting (negative sign), and if you need to move it to the other side of the equality, its sign changes to positive.

- If we have  an equality:  if the number is part of a product , and if you need to move it to the other side of the equality, the same number will be dividing the factors of the side.
