Answer:

x=-6

Step-by-step explanation:

The given equation is

2(x-3)-9=3x-9

Step 1: Using addition property of equality, add 9 on both sides.

2(x-3)-9+9=3x-9+9

2(x-3)=3x

Step 2: Using distributive property, we get

2(x)+2(-3)=3x

2x-6=3x

Step 3: Using addition property of equality twice we get

2x-6+6=3x+6

2x=3x+6

2x-3x=3x+6-3x

-x=6

Step 4: Using multiplication property of equality, multiply both sides by -1.

(-x)(-1)=(6)(-1)

x=-6

Therefore, the solution of the given equation is x=-6.

How would you solve this by elimination?
jekas [21]
To solve this equation by elimination, what you would do is multiply one of the equations by -1, or distribute -1 to each term in the equation, any of the 2 equations. Then align the equations and add them together.

-(X + 3y = 3)
-X - 3y = -3

-X - 3y = -3
X + 6y = 3
__________
3y = 0
y = 0/3 = 0.

Now we can solve for x, by simply plugging the value of y into any of the 2 equations.

X + 6y = 3
X + 6(0) = 3
X + 0 = 3
X = 3.

The solution to your system of equations would be (3,0).

Check this by plugging in the point to the other equation and see if it is true.

X + 3y = 3
(3) + 3(0) = 3
3 + 0 = 3
3 = 3.

Thus it is the solution.
