How do you solve -2(x + 3y) = 18

sergiy2304 [10]

solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

Step-by-step explanation:

We need to solve the equation: $-2(x + 3y) = 18$

Solving the equation:

$-2(x + 3y) = 18\\-2x-6y=18$

Simplifying and finding value of x:

$-2x-6y=18\\-2x=18+6y\\-2x/-2=18/-2+6y/-2\\x=-9-3y$

We can simplify and find value of y as well:

$-2x-6y=18\\-6y=18+2x\\-6y/-6=18/-6+2x/-6\\y=-3-1/3x$

So, solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

Whats the answer to this? Please help.

BaLLatris [955]

Answer:

The answer is just 1 and 3.

Step-by-step explanation:

To understand this problem, you must think of what whole numbers actually are.

Whole numbers consist of Positive integers and Zero.

Positive integers include 1, 2, 3, 4, 5, 6, ... etc

Zero is 0

The reason $\frac{23}{5}$ isn't a whole number is because that fraction doesn't reduce any further and does not yield a whole number.
