Solve for a

• a= -2

• a= -6

• a= 3

• a= 15

How many solutions does the equation below have?

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

3a + 9 + 4a = 2

• -1

• 1

• no solution

• -7

4(a + 3) = -32

• -11

• -44

• -20

• -8

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

Which equation will end in "no solution"?

• 2w - 11 = 3w + 5

• 2(w + 8) = 2(2w - 19)

• w + 7 + w = 2w - 9

• 2w - 6 = 2(w - 10) + 5w

Solve for a.

• a = pw

• a = p/w

• a = w/p

• a = w + p
