Translate into an equation:

One less than 4 times a number is 11

• 1-4n=11

• 4n-11=1

• 1-11=4n

• 4n-1=11

Translate into an equation:

Twice a number decreased by 5 is 7 more than the number.

• 5 - 2n = 7 + n

• 2n - 5 = 7 + n

• 5 - 2n = n +7

Solve: ¾x + 3y = 12

for x when y = 3

• y= 4

• x=6

• x=4

• y= 12
