Step-by-step explanation:
There's no value for x. After solving, there was no value for x. therefore x=0
What is the value of 3x plus 5y when x equal 12 and y equal 4
i really don't understand this question
i wiil give u a feedback
There are many ways to find 3 times 2 times 4
2*3*4
4*2*3
3*4*2
2*4*3
3*2*4
4*3*2
Hello,
Adding the 2 equations,
x+y+x-y=k+k ==>2x=2k==>x=k
if x=k, y=k-k=0
solution is (k,0)
