Explanation:
First multiply 3x+2y=15 by 2, and leave the value 10x-4y=2 alone. You would get 6x+4y=30.
6x+4y=30 Eliminate the +4y
10-4y=2 Eliminate the -4y
The answer would now be 16x=32 ----> 32÷16=2
So the value of x=2.
Not plug the value of x=2 into 3x+2y=15
3(2)+2y=15
6+2y=15
2y=15-6
2y=9
y=9/2= 4 1/2
So the values are:
x=2 y=9/2
Hope this helps!
