use the app “photomath” for these questions. they give you the answer and show you how to do it :) ❤️

Answer 2

I would double check these if I were you. Sometimes I make dumb mistakes, but here you go.

Answer:

2. x=13

4. x=0.5

6. x=-9

7. x=8

8. $x=\frac{-7}{2}$

9. $x=\frac{10}{3}$

10. x=4

11. x=5

12. $x=\frac{7}{4}$

Step-by-step explanation:

2.

$2(5x-3)=9x+7\\\\10x-6=9x+7\\\\x=13$

4.

$5(3x-1)-6x=3x-2\\\\9x-5=3x-2\\\\6x=3\\\\x=0.5$

6.

$5x=3(x-6)\\\\5x=3x-18\\\\2x=-18\\\\x=-9$

7.

$5x=2(x+12)\\\\5x=2x+24\\\\3x=24\\\\x=8$

8.

$7(2x-3)=20x\\\\14x-21=20x\\\\6x=-21\\\\x=\frac{-21}{6} =\frac{-7}{2}$

9.

$4(3x+5)=18x\\\\12x+20=18x\\\\6x=20\\\\x=\frac{20}{6} =\frac{10}{3}$

10.

$6(6-x)=3x\\\\36-6x=3x\\\\9x=36\\\\x=4$

11.

$5(8-x)=3x\\\\40-5x=3x\\\\8x=40\\\\x=5$

12.

$4(x+3)=12x-2\\\\4x+12=12x-2\\\\8x=14\\\\x=\frac{14}{8} =\frac{7}{4}$
