3 more than 8 times a number is 19

• 8n=19+3

• 8n-3=19

• 8n+3=19

• $\frac{8}{n}$ +3=19

• 3n+8=19

12 less than 7 times a number is 16

• 7n+12=16

• 7n-12=16

• 12-7n=16

• 12n-7=16

• 12n+7=16

4 more than twice a number is -10

• 2n-10=4

• 4-2n=-10

• 4n-2=-10

• 2n+4=-10

9 less than 5 times a number is -30

• 5n-9=-30

• 5n=-30-9

• 5n+9=-30

• 9-5n=-30

5 times the sum of a number and 3 is 9

• 5x + 3 = 9

• 3 + 5 = 9x

• 5(x + 3) = 9

• 5 + 3x = 9

8 time the difference of a number and 7 is 4

• 8( x - 7 ) = 4

• 8x - 7 = 4

• 7 - 8x = 4

• 4 = 7( 8 - x)
