Question

R + 354 = 1,321

Please include exact answer and correct explanation.

Answer 1

r = 967

Explanation:

When you have an equation, you have to keep the variables on one side of the equal sign and the numbers on the other side. But when you bring a number to another side it changes to the opposite, in this case addition to subtraction:

r + 354 = 1321 --

r = 1321 - 354

r = 967

Answer 2

Hello, there!

Pretend that the r is a question mark (?)

r + 354 = 1321

To solve this, we have to isolate the r.

r + 354 = 1321

-354 -354

r = 967

I hope I helped!
