9x+4x+10x -12+4
15x-8
Answer:
7 minutes
Step-by-step explanation:
okay so lets make blocks = x and neighborhood = y
2x + y =10
2x + 4y = 31
multiply the top equation by -1 so we can single out y
-2x - y = -10
2x + 4y = 31
combine the two equations
3y = 21
since the x's have canceled each other out, just divide both sides by 3 to get a single y
y = 7
