Get b by itself! Get rid of the 1/2 by multiplying both sides by 2. Then, divide by h.

Leah has $12 less than 5 times the amount Edward has.

Which expression represents Leah’s amount if Edward has d dollars?

• L = 12 - 5d

• L = 5d - 12

• L = 5d + 12

Solve: 3(x+7)-5x = 12

• x = 2/9

• x = 4/5

• x = 5/4

• x = 9/2

• 2

• 4

• 6

• 8

Answer explanation

Plug into Desmos :) Use x!

• Multiply both sides by -2

• Multiply both sides by 2

• Divide both sides by -2

• Divide both sides by 10

Which equation has no solution?

hint: no solution means that the variables cancel (same on both sides) and then you're left with a false statement

• -2

• 2

• 4

• -4

• 10

• 8

• 6

• 4
