Answer: The blank space in the equation is 4.
Step-by-step explanation: -6 x +2 is -12. -48/-12 is 4. Therefore, the blank space in the equation is 4.
Answer:
Reduce the greatest common factor on both sides of the equation: (2x+y=12
(x-3y=27
Rearrange like terms to the same side of the equation: (2x+y= 12
(x=27+3y
Substitute into one of the equations: 2(27+3y)+y=12
Apply Multiplicative Distribution Law: 54+6y +y=12
Rearrange unknown terms to the left side of the equation: 6y+y=12-54
Combine like terms: 7y=12-54
Calculate the sum or difference: 7y=-42
Divide both sides of the equation by the coefficient of variable: y= -42÷7
Calculate the product or quotient: y= -6
Substitute into one of the equations: x=27+3×( -6)
Remove the parentheses: x=27-3×6
Calculate the product or quotient: x=27-18
Calculate the sum or difference: x=9
The solution of the system is: x=9
y=-6
Answer:
x=9
y=-6
You could layout the question like this:
3 hot dogs = 2 minutes
x hot dogs = 7 minutes
In order to get from 2 minutes to 7 minutes, we could divide by 2 and then multiply by 7. So let’s do that to both sides.
3/2 = 1.5 x 7 = 10.5.
Therefore,
3 hot dogs = 2 minutes
10.5 hot dogs = 7 minutes
