Question

HELP ME PLEASE r − 3 = 4

Answer 1

Answer:

r = 7

Step-by-step explanation:

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 3 to both sides of the equation:

r - 3 = 4

r - 3 (+3) = 4 (+3)

r = 4 + 3

Simplify. Combine like terms:

r = 4 + 3

r = 7

r = 7 is your answer.
