Answer:
32
Step-by-step explanation:
12/3=4
45/3=15-4-7=4 * the witch doesn't have a wand or spoon like the top row does.
21/3=7
4+4x7*order of operations
4+28
32
Y = -6x + 2 . . . . . . . . (1)
-12x - 2y = -4 . . . . . . (2)
Putting (1) into (2), we have
-12x - 2(-6x + 2) = -4
-12x + 12x - 4 = -4
-4 = -4
Therefore, the system has infinite number of solutions.
H = V/bl. You just cross multiply
