Answer 1

Explicación paso a paso:

4x+9+x=24

5x = 24-9

5x=15

➡️x=3⬅️

9+7x-3-4x=27

3x+6=27

3x=27 -6

3x=21

x=21/3

➡️x=7⬅️

2(x+3=10

2x+6=10

2x=10-6

2x=4

➡️x=2⬅️

5(x+8=50

5x+40=50

5x=50-40

5x=10

➡️x=2⬅️

3(2x-5=9

6x-15=9

6x=9+15

6x= 24

x=24/6

➡️x=4⬅️

8(5+x)=6x+52

40+8x=6x+52

8x-6x=52-40

2x= 12

x=12/2

➡️x=6⬅️

4(x+1-20)=28

4x+4-80=28

4x-76=28

4x= 28+ 76

4x= 104

x=104/4

➡️x= 26⬅️

2(x-3)=3(x-4)

2x-6=3x-12

-6+12= 3x -2x

6= x

➡️x=6⬅️

2(x-5)+3(x+5)=20

2x-10 + 3x+15 =20

5x+5=20

5x=20-5

5x=15

x=15/5

➡️x=3⬅️

4(2x+3)+5(3x-6)=5

8x+12 + 15x-30=5

23x-18=5

23x= 5 + 18

23x= 23

x= 23/23

➡️x=1⬅️
