They give you an "x =" statement so you plug in the right side of the equals sign into the first equation wherever x appears. So...
y = 10 - 2(y - 4)
y = 10 - 2y + 8
y = 18 - 2y
y + 2y = 18
3y = 18
y = 6
Now we plug in this result for the y-value into the "x =" statement.
x = 6 - 4
x = 2
Your answer is (2, 6)
Answer:
335
Step-by-step explanation:
536/336 = x/210
Answer:
- To solve the following equation we must first combine like terms
- Recognize the easiest way to manipulate the equation
- Lastly rearrange to isolate for x: usually done with division
2x+3x-11x-6=0
Combine like x variables
-6x-6=0
Add 6 to the right side
-6x = 6
Divide by -6
x=-1
