Scholar #2 is correct. You take 15=-3m-18+5m-7 and combie like terms. Which will leave you with 15=2m-25. You will simplify from there, getting 20=m.
15 = -3m - 18 +5m -7
First step is to combine like terms:
15 = 2m - 18 - 7
15 = 2m-25
Add 25 to each side:
40 = 2m
Divide both sides by 2:
m = 40/2
m = 20
Scholar 2 has the correct solution.

2^1 because when you times indices you add the indices and when you divide you subtract it
Answer:
2x + 7 = 3x - 7
3x - 2x = 7 + 7
x = 14
2x + 7 + 12y + 1 = 180
2(14) + 12y + 8 = 180
28 + 12y + 8 = 180
36 + 12y = 180
12y = 180 - 36 = 144
y = 144/12 = 12
x = 14, y = 12
Answer:
76 cm
Step-by-step explanation:
P=2L+2w
324=2(86)+2w
324=172+2w
324-172=2w
2w=152
w=152/2
w=76 cm
