What is the value of the variable in the equation, r-17=22 * please help me with this for brainliest and a cupcake

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7,  or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).
