Answer:

9) x=58

10) r=4

11) m=4

12) p=3

13) x=6

14) x=-3

15) s=400

Step-by-step explanation:

9) x+2/5=12

    x5  x5

x+2=60

 -2  -2

x=58

10) 7r + 14 - 3r =30

    -14         -14

<u>7r-3r</u>=16

4r=16

÷4 ÷4

r=4

11) \frac{4}{5}m+2=6

    -2  -2

\frac{4}{5}m=4

÷\frac{4}{5}  ÷\frac{4}{5}

m=4

12) <u>2</u>(5p+9)=48

10p+18=48

     -18  -18

10p=30

÷10  ÷10

p=3

13) <u>5</u>(2x-8)=20

10x-40=20

    +40 +40

10x=60

÷10  ÷10

x=6

14)<u>6</u>(3-2x)=54

18-12x=54

-18       -18

-12x=36

÷-12  ÷-12

x=-3

15) \frac{2s}{5}-\frac{s}{2}=40

x5   x5

2s-\frac{s}{2}=200

    x2 x2

<u>2s-1s</u>=400

1s=400

÷1  ÷1

s=400
