8m - 5n + 2m + 6n =Simplifying
8m + -5n + 2m + 6n = 0
Reorder the terms:
8m + 2m + -5n + 6n = 0
Combine like terms: 8m + 2m = 10m
10m + -5n + 6n = 0
Combine like terms: -5n + 6n = 1n
10m + 1n = 0
Solving
10m + 1n = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1n' to each side of the equation.
10m + 1n + -1n = 0 + -1n
Combine like terms: 1n + -1n = 0
10m + 0 = 0 + -1n
10m = 0 + -1n
Remove the zero:
10m = -1n
Divide each side by '10'.
m = -0.1n
Simplifying
m = -0.1n.
Answer:

Step-by-step explanation:
Jose=x-12
Rachael=x-12/2
sum of their ages x-12+x-12/2=63
collect like terms
x=54years
Jose =54years
Rachael=38years
Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
