Question

Solve the following equations:-
1. 5-3m=20
2. 1-7y=-6
3. 2-3a+7=8a+3-a
4. 8x-16=6x+6
5. 25m-10=21m+14
6. 3(7a+3)=4(6a+2)
7. 3(1+y)+7(3+y)=11y
8. 7(7-2y)-11(11-2y)=0​

Answer 1

Answer:

hey...

here is your answer...

1) 5-3m =20

= -3m =20-5

= -3m =15.

= -m =15/3

= - m = 5

= m =-5

2) 1-7y = -6

=-7y = -7

= y = 1

3) 2-3a +7 =8a +3-a

4 ) 8x -16 = 6x +6

= 8* -6* = 6+16

= 2* = 32

= * = 16

5) 25m -10 = 21 m +14

= 25m -21m = 14+10

= 4m =24

= m =24/4

= m =8

6) 3( 7a + 3) = 4( 6a +2)

= 21 a +9 = 24 a +8

= 9-8 = 24 a -21 a

=1 = 3a

= a= 1/3

Answer 2

Answer:

hola..

==>>

1) 5- 3m=20. 2) 1-7y=-6

-3m =20-5. -7. = -6-1

-3m=15. -7 y.= -7

m = 15/ -3. y = 1

m = -5

3) 2-3a +7 =8a +3-a

9-3a = 5a

9 = 5a +3a

9 = 8a

a = 9/8

4) 8x -16= 6*+6

8*-6* = 6+16

2* = 32

x = 32/2

x =16

5) 25m -10 = 21m +14

25m-21m = 14+10

4 m = 24

m = 24/4

m = 6

6) 3( 7a +3 )= 4(6a+2)

21 a+9 = 24 a + 8

9-8 = 24 a-21 a

1= 3 a

a = 1/3

7) 3(1+y ) +7( 3+y ) =11y

3 +3y +21 +7y =11y

24 +10y =11y

24 =11y -10y

24 = y

8) 7(7 -2y ) -11(11-2y ) = 0

49 -14.y -22 +22y =0

27 +8y = 0

8y = -27

y = -27/8
