Answer 1

Explicación paso a paso:

5x=65-5

5×=60

×=60/5 ×=12

15+3a=-6

15+6=-3a

21= -3a

a=-7

4x+6=-x-14

4×+×= -14-6

5×=-20

×= -20/5

×= -4

3y+6=-30+2y

3y-2y= -30-6

y= -36

4(8-4n)=2(n-40)+4

32-16n = 2n-80+4

-16n-2n= -76-32

-18n= -108

n=108/18

n=6

y -3y-6=28

-2y-6=28

-2y=28+6

-2y=34

y= -34/2

y= -17

m+14-2m=-8

-m=-8-14

-m= -22

m=22

-6×+8=2×+64

-6×-2×=64-8

-8× =56

×=-7

2(6+5×)-11=71

12+10×=71+11

10×=82-12

10×=70

×=7

6(2×+5)=-3(-×+2)

12×+30=3×-6

12×-3×=-6-30

9×= -36

×= -4
