F) X+5=11 G)5x=4x+12 H)2x=24 I)2x= -40 J)7x=1 K)9x=5 L)3m=12 M)3y+1=13?​

Answer 1

F) =6 G)= 12 H)= 12 I)= -20 J)=0,142... K)= 0,555 L)=4 M)=4

Explicação passo-a-passo:

x+5=11

x=11-5

x=6

5x=4x+12

5x-4x=12

x=12

2x=24

x=24÷2

x=12

2x=-40

x=-40÷2

x= -20

7x=1

x=1÷7

x=0,142...

9x=5

x=5÷9

x=0,555...

3m=12

m=12÷3

m=4

3y+1=13

3y=13-1

3y=12

y=12÷3

y=4
