The correct answer to the question is option A. r = -3
What are linear equalities in one variable?
The linear equation in one variable is an equation that is expressed within the form of ax+b = zero, where a and b are integers, and x is a variable and has only one answer.
Conclusion: For example, 2x+3=8 is a linear equation having a single variable in it. therefore, this equation has only one solution, which is x = 5/2.
2(4r + 4) = -16
8r + 8 = -16
8r = -16 - 8
8r = -24
r = -24/8
r = -3
