Question

Part 1: Explain, in complete sentences, how you would use the elimination method to solve the following system of equations. (3 points) 

Part 2: Provide the solution to the system. (1 point) 

2x + 9y = 4 
3x + 7y = –7

anonymous · Answer

2x + 9y = 4 ...............1  mul. by 3
3x + 7y = –7................2 mul. by -2

6x  +27y=12...............1
-6x -14y=14...............2
----------------
0 +13 y = 26
y=2
sub y in equation 1
2x+(9×2)=4 ----> 2x=4-18
x=-7
