Twice the difference of a number and 5 is equal to three times the sum of the number and 4. Find the number

Question

Find the number

Answer 1

twice the difference of a number and five is 2(x-5).

three times the sum of the number and 4 is 3(x+4)

 

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

2x-10 = 3x + 12

x = -22

 

check:  2(-22-5) = 3(-22+4)

            -54 = -54
