<span>The y variable has the same coefficient so use elimination (subtract equations).
-2x = 8 - 6y
-(-15x = 21 - 6y)
------------------------
13x = -13 + 0
x = -1
Use this to find y in either equation. </span>
<span>-2(-1) = 8 - 6y
2 = 8 - 6y
2 - 8 = -6y
-6 = -6y
y = 1
(x,y) = (-1, 1)
</span>
The answer to the equation is 9 I hope this helps you
Answer:
Let Ishaan's age be x. Then, Christopher's age is x-20. These are their current ages.
14 years ago,
x-14 = 3(x-20-14) (we need to subtract 14 from both of their ages')
x - 14 = 3(x - 34)
x - 14 = 3x - 102
2x = 88
x = 44
Ishaan is 44 years old now.
Answer:
8 scoops of flour
Step-by-step explanation:
Set up a proportion so,
(5/25)=(x/40) *Solve for X*
25x = 200
x = 8
We are first given f(x) = 7x. The line is then changed to f(x) = 7x + 7 by moving the graph up 7 units on the y-axis.
Direction: THE GRAPH IS MOVED UPWARD.
