1 is C, since it is anything less than 8, so 7 times 2 is 14 minus 2 is 12.
2 is C, since it is anything less than 8, so 7 times 3 is 21, and 1 minus 21 is -20.
The opposite of multiplication is division, so you divide 2 from both sides.
R2/2 = cancel out
6.25/2 = 3.125
R = 3.125
-3.6
Step-by-step explanation:
z/(-2) + -5 = -3.2 → times -2
z + 10 = 6.4
z = 6.4 - 10
z = -3.6
