Answer:
r = -3
Step-by-step explanation:
Performing the indicated multiplication on both sides of this equation, we get:
5r - 5 = 2r - 8 - 6
Combining the r terms: 3r - 5 = - 8 - 6.
Combining the constants: 3r = 5 - 14, or 3r = -9.
Dividing both sides by 3, to isolate r, we get: r = -3
L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2
