14(6x - 3) = 99(22)

<u>Distribute 14 and 99:</u>

84x - 42 = 2178

<u>Add 42 to both side:</u>

84x = 2220

<u>Divide both sides by 84:</u>

x = 26 3/7

Answer: x = 26 3/7

First you'd need to multiply 99 by 22.

14 ( 6x - 3 ) = 99 × 22

14 ( 6x - 3 ) = 2,178

Next, you'd divide both sides by 14.

14 ( 6x - 3 ) = 2,178

\displaystyle\frac{14(6x-3)}{14} = \frac{2,178}{14}

\displaystyle\ 6x - 3 = \frac{2,178}{14}

Now simplify 2,178 over 14.

\displaystyle\ 6x - 3 = \frac{2,178}{14}

\displaystyle\ 6x - 3 = \frac{1,089}{7}

Now add 3 to both sides to get rid of -3.

\displaystyle\ 6x - 3 = \frac{1,089}{7}

\displaystyle\ 6x - 3 + 3= \frac{1,089}{7} + 3

\displaystyle\ 6x = \frac{1,110}{7}

Now divide both sides by 6 to get x alone.

\displaystyle\ 6x = \frac{1,110}{7}

\displaystyle\frac{6x}{6} = \frac{\frac{1,110}{7}}{6}

\displaystyle\ x  = \frac{185}{7}

Now we simplify.

\displaystyle\ x  = \frac{185}{7}

\displaystyle\ x = 26\frac{3}{7}

2+d=2-3(d-5)-2 Pls show work
defon
2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: d = -3(d - 5) - 2
Second, expand. / Your problem should look like: d = -3d + 15 - 2
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: d = -3d + 13
Fourth, add 3d to both sides. / Your problem should look like: d + 3d = 13
Fifth, add d + 3d to get 4d. / Your problem should look like: 4d = 13
Sixth, divide both sides by 4. / Your problem should look like: d =  \frac{13}{4}

Answer as fraction: d =  \frac{13}{4}
Answer as decimal: d = 3.25
