x = y + 8 => x = -7/2 + 8 => x = 9/2.
Answer:
x = 4.5 and y = -3.5
Step-by-step explanation:
To find the solution to this system of equations using the substitution method, you must solve for either the x or y variable and then substitute into the other equation.
x = (y + 8)
5x + 3y = 12
We will use the first equation to solve for x. The x has to be isolated on one side. Since the first equation already has x on the one side, we can plug it into the other equation.
5(y+8) + 3y = 12
Distribute and solve:
5y + 40 + 3y = 12
8y + 40 = 12
8y = 12-40
8y = -28
y = -3.5
Now we have the y variable, we can plug that back into the first equation to find x.
x = (-3.5) + 8
x= 4.5
Your answer will be x = 4.5 and y = -3.5

Final answer:
The fraction 30/7 approximates to 4.28, which isn't a whole number. However, rounding down to the nearest whole gives us 4. Hence, 30/7 as a whole number is 4.
Explanation:
The question is asking to express the fraction 30/7 as a whole number. To accomplish this, you would divide the numerator (30) by the denominator (7). The result of that operation is approximately 4.28, which isn't a whole number. But if we need to present it as a whole number, we round down to the nearest whole number. So, 30/7 as a whole number is 4. Just remember that 30 is not perfectly divisible by 7, therefore rounding is required for a whole number representation.
