Question:

What is the result for the following problem? x+x+x=60 x+y+ý=30 y-2z=3 z+x*y=?

We can set x as 20, so 20+20+20 = 60 now let try the next part, we can set y as 5 so we have for the second equation 20 + 5+ 5=30 so we are good so far. now for the third one 5-2z=3, we can solve it for -2z=3-5, z=-2/-2 , z=1 now for the last part. We have 1+20*5=? remember the order of operations, so we need to do first the multiplications then the addition. so we have 20*5=100 now the addition 100+1=101 that is the answer
