Solve for x
2(x - 2) = 6
First distribute 2 to both x and -2
2(x) = 2x
2(-2) = -4
2x - 4 = 6
Next, isolate the x. Do the opposite of PEMDAS. Add 4 to both sides
2x - 4 (+4) = 6 (+4)
2x = 6 + 4
2x = 10
Finally, to isolate the x, divide 2 from both sides
2x/2 = 10/2
x = 10/2
x = 5
5 is your answer for x
hope this helps
Hi!
First, let's use the distribution property.
To do that, multiply the values in the parentheses by the number outside of the parentheses.
2 · x = 2x
2 · -2 = -4
2x - 4 = 6
Remember that whatever we do to the equation we have to do it to both sides.
We need to isolate x on one side. So first let's add 4 to both sides.
2x - 4 + 4 = 6 + 4
2x = 10
Divide by 2 on both sides.
2x/2 = 10/2
x = 5
The answer is x = 5
Hope this helps! :)

Answer: 
<u>Step-by-step explanation:</u>


Insert x = 13 and y = 1:
x² + 2hxy + 12y² = 0
(13)² + 2(13)(1) + 12(1)² = 0
169 + 26h + 12 = 0
26h + 181 = 0
26h = -181
