Try box be<br> 1) Solve for m: 2m + 21 = 3<br> Help please…

Viktor [21]

first step is to subtract 21 from both sides

2m+21-21=3-21

2m=-18

2m/2 and -18/2

m=-9

So the final answer is m=-9 (negative nine equals m)

Answer:

y=20

Step-by-step explanation:

0.6(y-10)=6

0.6y-6=6

0.6y=6+6

0.6y=12

y=12/0.6

y=20

1/(x-2)+1/(x+3)=1/5 solve the problem for me

<h3>Final value : x² -9x - 11</h3>

════════════════════

$\frac{1}{(x - 2)} + \frac{1}{(x + 3)} = \frac{1}{5}$

$\frac{(x + 3) + (x - 2)}{(x - 2)(x + 3)} = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + 3x - 2x - 6 } = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + x - 6} = \frac{1}{5}$

2x + 1 = ⅕ × (x² + x - 6)

2x + 1 = ⅕x² + ⅕x - 6/5

1/5x² +1/5x - 2x - 6/5 - 1 = 0

1/5x² -9/5x - 11/5 = 0

x² - 9x - 11 = 0. #times by 5
