Answer: R=0
Step-by-step explanation:
Answer:
r = 0
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.

27+64
lmk if you need an explanation
step 3: he should have divided both sides by -7
x= 80
y= 77
180-23=157
80+77=157
157+23=180
