Answer:
Multiply by 3;9
Step-by-step explanation:
9/3=3
12/4=3
18/6=3
27/n=3
N=9
The given equations satisfy the given conditions. There are
2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
1. Write out the problem: 3x+12/3
2. Find the common factor: 3(x+4)/3
3. Cancel out the threes.
4. Once you cancel them out you get: x+4
