Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:
In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,
Dividing both sides by 3, we get:
Now, 
Therefore, the solution is (-2, -4)
1. A. y and 1.2y are like terms. c they both contain the same term (y) and can therefore be combined.
2. B. 12x+11 (you have to combine the like terms)
3. 15y+18-4
C. 15y+14 (you must distribute the 3 to inside the parentheses, so 3×5y and 3×6)
4. 9(9-3p) (you have to find a common factor between the terms, in this case 9, and you place it on the outside of the parentheses, while dividing that factor from those terms, which are placed in parentheses.
Answer:
3x=42
Divide 3x to both sides
14=x
56=8x
Divide 8 to both sides
7=6
6x+4=40
subtract 4 to both sides
6x=36
divide 6 to both sides
x=6
58=4x-6
add 6 to both sides
64=4x
divide 4 to both sides
16=x
