So maybe it’s 5, it’s equivalent to the side with 6, just shorter
<span>Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8.
Simplify Q - [R + S] - T.
Q-(R+S)-T
=</span>7m + 3n - (11 - 2m + n + 5 ) - (-m - 3n + 8)
=7m+2m+m + 3n-n+3n -11-5-8
=10m+5n-24
If you want the answer to be 60 you could put 30+30=60
Answer:
x + 3
Step-by-step explanation:
Given
(8x - 6) - (7x - 9)
Distribute the first parenthesis by 1 and the second by - 1
= 8x - 6 - 7x + 9 ← collect like terms
= x + 3
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
