Answer:
m = (8+3n)/4
k = 55j+20
Step-by-step explanation:
4m -3n = 8
Add 3n to each side
4m-3n+3n = 8+3n
4m = 8+3n
Divide by 4
4m/4 = (8+3n)/4
m = (8+3n)/4
(k-20)/5 = 11j
Multiply each side by 5
(k-20)/5 *5= 11j*5
k-20 = 55j
Add 20 to each side
k-20+20 = 55j+20
k = 55j+20
Use Substitution or Elimination
1. pick one equation and solve for a variable
6p + 1m = 9
1m = 9-6p
m = 9 - 6p/ 1
m= 9-6p
2. substitute m into one of the equations given
4p + 2 ( 9-6p) = 10
4p + 18 - 12p = 10
4p - 12p = 10 - 18
-8p = -8 (divide both sides by -8)
p = 1
3. Insert p=1 into any of the equations
6p+1m = 9
6(1)+1m =9
6 + 1m = 9
1m = 9-6
1m= 3
m = 3
