Answer:
Step-by-step explanation:
we have
step 1
Group terms that contain the same variable, and move the constant to the opposite side of the equation
step 2
Factor 5 left side
step 3
Complete the square
step 4
Rewrite as perfect squares
step 5
step 6
Answer:
X=1 9/10
Step-by-step explanation:
6X multiply 2 - 2X=19
Calculate the product
12X-2X=19
Collect the like terms
10X=19
Divide both sides of the equation by 10
X=19/10
Simplify the improper fraction
X=1 9/10
9514 1404 393
Answer:
zero
Step-by-step explanation:
Dividing the second equation by -3, it becomes ...
x -3y = 7/3
Compared to the first equation, ...
x -3y = 5
we see that it is <em>inconsistent</em>. No values of the variables can satisfy both equations. There are no solutions.
N = the number
9/10n + 6 = 51 Original Problem.
9/10n = 46 Subtract 6 from each side.
n = 51.11111111111111111111 Multiply each side by (10/9)
Answer: n = 51.111111111111111111111
