If they all have the same variable it will be much easier to solve cause they’re all like terms. so you just take 10-5 which is 5 plus 3 which is 8 and 8 minus 8 is 0.
Answer:
c) 14/5 = 2.8 each (better value)
Step-by-step explanation:
a) 9/3 = 3 each
b) 28/7 = 4 each
c) 14/5 = 2.8 each (better value)
Answer:
The solution to the system of equations is y = -5 and x = -2.
Step-by-step explanation:
The question tells us to use substitution to solve the system. This means that the given value for x (in terms of y) should be substituted into the other equation. This is modeled below:
-4y - 5x = 30
-4y - 5(y+3) = 30
Next, we should use the distributive property to simplify the left side of the equation.
-4y -5y - 15 = 30
The next step is to combine like terms on the left side of the equation.
-9y - 15 = 30
Then, we can add 15 to both sides of the equation.
-9y = 45
Finally, we can divide both sides of the equation by -9.
y = -5
To find the value for x, we substitute in the value we just found for y into either of our original equations.
x = y + 3
x = -5 + 3
x = -2
Therefore, the correct answer is y = -5 and x = -2.
