1-(-18)= 19
sense the subtract and negative cancel out, look at it as a plus sign between 1 and 18 so 1+18=19
Answer:
I think it's (x+16, y)
Step-by-step explanation:
You add your x's 2+4= 6x and do the same with your y's 4-2= 2y you do with with ONLY X's with X's and Y's with Y's bc they are like terms
6x+2y should be your answer
X+(x+1)+(x+2)=72
3x=72-3
3x=69
X=23
23+24+25= 72
57
2^2=4
4+4=8
6*8=48
48+9=57
