The correct answer is:
A. 14x+6y= 10
-14X-35y=77
Further explanation:
One method of solving system of linear equations in two variables is elimination method. In this method, the co-efficient of one variable have to be equated so that variable can be removed to get the value of other variable.
Given equations are:
As we have to eliminate x, then the co-efficient of x will be equated. For this purpose both equations will be multiplied with some constant.
So,
multiplying equation one with 2
Multiplying equation 2 by -7
So,
The correct answer is:
A. 14x+6y= 10
-14X-35y=77

-14,-10,-6,-2,2,6
Answer by Mimiwhatsup: I could easily subtract -14 from -10 to find out the sequence so they are adding four each time. That means the pattern will continue going on like this 10, 14, 18, 22 and so forth.
Answer:
answer D
Step-by-step explanation:
A and C have to be equal
B and D have to be equal
A+B+C+D have to equal 360
so, two equations
5y-3=x+3y
4x+5y-3+x+3y=360
4x=156
x=39
5y-3=9+3y
2y=42
y=21
Hope this helps plz hit the crown :D
