The answer is 1/3 because I just took the test
Add 7 and 7 which is 14 and then take it apart because it is an even number
Answer:
The solution is x=3 , y=-4 or (3,-4)
Step-by-step explanation:
Given equations (1 and 2) are:

To solve a system of equation with elimination method, the co-efficients of one of the variables has to be equated and then the equations are added or subtracted to get an equation in one variable.
Multiplying equation 1 by 2:

Multiplying equation 2 by 3

Adding equation 3 and 4

Putting y = -4 in equation 1

Hence,
The solution is x=3 , y=-4 or (3,-4)
C) x = -19/10 because when solving it with substitution u get x=-19/10 & y=153/10
Answer:

Step-by-step explanation:
Given

Required
Gaps: -2( )-2( )=8
<em>Fill in in the gaps</em>
The are numerous solutions to this.
One of them is:
Assume y = 0.
So, we have:



Divide through by -2


Fill in the gaps with these values of x and y respectively:
Hence; one solution is:
