Answer 1

Respuesta:

a = 3

m = -3

s = 7

f = 6

r = -1

x= -6

Explicación paso a paso:

9a-8 = 5a+4

9a-5a = 8+4

4a = 12

a =12/4

a = 3

-7m-5 = -5m+1

-7m+5m = 5+1

-2m = 6

m = 6/-2

m = -3

3s+7 = 4s

7 = 4s-3s

7 = s

s = 7

8f+2 = 10f-10

2+10 = 10f-8f

12 = 2f

f=12/2

f=6

7r+5 = 5r+3

7r-5r = 3-5

2r = -2

r = -2/2

r = -1

4x+16 = 2x+4

4x-2x = 4-16

2x = -12

x = -12/2

x = -6
