Four more than twice a number is 8.

• 8n + 4 = 2

• 4n + 2 = 8

• 2n + 8 = 4

• 2n + 4 = 8

Three more than four times a number is 15.

• 4x + 3 = 15

• 3x + 4 = 15

• 4x + 15 = 3

• 15x + 3 = 4

Seven more than the quotient of a number and 2 is 10.

• 2/m + 7 = 10

• n/7 + 2 = 10

• n/2 + 7 = 10

• n/2 + 10 = 7

331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

• 7x+6=331

• 13x=331

• 6x+7=331

• 331-7=6x

solve the equation: 2x - 6 = 12

x=
