10x - 4y = 5 (if it requires shorten)
Step-by-step explanation:
x + y/5 - 1 = y - x
<=> (5x + y - 1.5)/5 = 5(y - x)/5
<=> 5x + y - 5 = 5y - 5x
<=> 5x + 5x + y - 5y = 5
<=> 10x - 4y = 5
Answer:
Roots of the equation are (−3−√7) , (−3+√7)
Step-by-step explanation:
For solving a quadratic equation using completing the square method:
- set the value of 'y' = 0
- add and subtract the square of half of the coefficient of x.
- solve the obtained equation for 'x'
given equation:
y = x^2 - 6x +2
0 = x^2 - 6x + 2
0 = x^2 - 3^2 + 3^2 -6x +2
0 = (x-3)^2 -7
7 = (x-3)^2
±
= x-3
±
+ 3 = x

Answer:
441
Step-by-step explanation:
Use a proportion.
756 miles is to 12 hours as x miles is to 7 hours
756/12 = x/7
12x = 7 * 756
12x = 5292
x = 441
Answer: 441 miles
Answer:
x = 21.3 repeating. so put the - on top of the 3 if you're writing it down
Answer: The answers are x=y/3–4/3, and x=y/9–10/9.
Step-by-step explanation: You’ll need to isolate the variable by dividing each side by factors that don't contain the variable.
