Answer:
n = 4, m = 1
Step-by-step explanation:
Given the 2 equations
3m + n = 7 → (1)
m + 2n = 9 → (2)
Rearrange (2) expressing m in terms of n, by subtracting 2n from both sides
m = 9 - 2n → (3)
Substitute m = 9 - 2n into (1)
3(9 - 2n) + n = 7 ← distribute left side
27 - 6n + n = 7 ← simplify left side
27 - 5n = 7 ( subtract 27 from both sides )
- 5n = - 20 ( divide both sides by - 5 )
n = 4
Substitute n = 4 into (3) for corresponding value of m
m = 9 - (2 × 4) = 9 - 8 = 1
Thus m = 1 and n = 4
Answer:
borh are correct in the same order that you wrote them. fist you eliminate 1 from the orinal side to the other so the next step is also right you subtrac 8 mines 1 so equal to 7 ...
Answer:
Real Part = -5
Imaginary part = -1
Step-by-step explanation:
We need to describe each part of the complex number: 
Complex Number
A complex number is of form<u> </u>
where a is real part while b represents the imaginary unit.
In the given complex number:
Real Part = -5
Imaginary part = -1
It will be 6/10 becausebif u leave the denominator ofn10 becausenthey ar the same then u add 3+3 which equals 6 wo the answer is 6/10
