Answer:
x = 25
Step-by-step explanation:
In any triangle, the sum of all 3 angles is ALWAYS 180 degrees. So we can make this into an equation.
4x + 2x+ 10 + x - 5 = 180
Now we combine the like terms.
7x + 5 = 180
Subtract 5 from both sides.
7x = 175
Now divide by 7 on both sides.
x = 25
The LCD is 12. Thus, your
(x-2)/4 - (x+3)/3 = -2 becomes 12((x-2)/4 - (x+3)/3 = -2), or
3(x-2) - 4(x+3) = -36
Then 3x - 6 - 4x - 12 = -36. Combining like terms,
-x = -36 + 18, or -x = -18, or x = 18.
Check this result by subbing 18 for x in the given equation.
Please note: You must use parentheses here as indicated to eliminate any ambiguity about order of operations and what divides into what.
