Question

solve the following equation and check your answer 3x÷2+4÷5=31÷20​

Answer 1

Answer:

x = -3/10

Step-by-step explanation:

3x ÷ 2 + 4 ÷ 5 = 31 ÷ 20

3x/2 + 4/5 = 31/20

(15x + 20)/10 = 31/20

(15x + 20) = 31/2

2(15x + 20) = 31

30x + 40 = 31

30x = 31 - 40

30x = -9

x = -9 ÷ 30

x = -3 /10

Answer 2

Answer:

1/2

Step-by-step explanation:

3x/2+4/5=31/20

(15x+8)/10=31/20

15x=31/2-8

15x= 31-16/2=15/2

x=1/2
