Answer:
x = 11
Step-by-step explanation:
the line x + 5 is a mid segment of the triangle and thus is half the length of 3x - 1, that is
x + 5 = 
(3x - 1)
multiply both sides by 2 to eliminate the fraction
2x + 10 = 3x - 1 ( subtract 3x from both sides )
- x + 10 = - 1 ( subtract 10 from both sides )
- x = - 11 ( multiply both sides by - 1 )
x = 11
What equation please tell me
What if I wrote + 38 - 28 .
Would you be able to solve it that way ?
They're both the same number.
The answer is <span>10 was added to each side.
</span>
<span>x² + 8x + 60 = x² + 12x + 20
____
Subtract x</span>² from both sides:
x² + 8x + 60 - x² = x² + 12x + 20 - x²
8x + 60 = 12x + 20
60 - 20 = 12x - 8x
40 = 4x
x = 40/4
x = 10
So, 10 was added to each side.
