Answer: The answer is 3/8
Step-by-step explanation: First you figure out your expression: 7/8 - 1/2. Then you find a common denominator, which will be 8. To make one-half have a denominator of 8, multiply by 4/4. 1/2*4/4=4/8. To finish, subtract 7/8-4/8 and you get 3/8.
Answer:
The system of equations does not have a solution
Step-by-step explanation:
Whenever you get a number = a different number, that means there's no solution.
x = 2
1/2(x + 12) = 4x - 1
1/2x + 12/2 = 4x - 1
1/2x + 6 = 4x - 1
1/2x - 4x = -1 - 6
1/2x - 8/2x = -7
-7/2x = -7
x = -14/-7
