Question

Me ajudem com essa equação de 1 grau

1) 15x + 10 = 10x + 50

2) 2x + x - 5 = 10

3) x/2 = 20

4) x/3 = 30

5) x/5 = 10

6) x/2 = 15

7) x/16 = 5

8) x/2 - 5 = 10

9) 5x + x/2 = 50

Answer 1

1) 15x + 10 = 10x + 50
15x - 10x = 50 - 10
5x = 40
x=40/5
x=8

2)2x + x -5 = 10
2x + x = 10 +5
3x = 15
x=15/3
x=5

3) x/2=20
x=20.2
x=40

4)x/3=30
x=30.3
x=90

5)x/5 = 10
x=10.5
x=50

6)x/2=15
x=15.2
x=30

7)x/16=5
x=5.16
x=80

8)x/2 - 5 = 10
x/2=10+5
x/2=15
x=15.2
x=30

Answer 2

1) 15x+10=10x+50
15x-10x= 50-10
5x=40
x=40÷5
x= 8

2)2x+x-5=10
2x+x=10+5
3x=15
x=15÷3
x=5


3)x/2=20
x=20×2
x=40

4)x/3=30
x=30×3
x=90

5) x/5=10
x= 10×5
x=50

6)x/2=15
x=15×2
x=30

7)x/16=5
x= 5×16
x=80

8)x/2 - 5=10
x-10= 20
x=20+10
x=30

9)5x+x/2=50
10x+x=100
11x=100
x=100/11
