Determine all that have the solution x = 3

A. 3x + 4 = 15

B. -2x - 5 = -11

C. x/3 + 5 = 6

D. 2/5x + 4/5 = 2

B, C, and D are correct

200

What should you do first?

3(4x + 8) = 20

Distribute 3 to the group (4x + 8)

The difference between twice a number and 11 is 21

La diferencia entre el doble de un numero y 11 es 21

2x-11=21 and x=16

300
Determine all that have the solution y = -2

A. -3y + 4 = 10

B.  15 = 4y + 23

C. 0 = y - 2

A and B are correct

300

What is the second step?

-20y + 14 = 32

Divide both sides by -20

2x-3=5 and x=4

400

Which equations do NOT have a solution of b = 11

A.  4b + 1 = 45

B. 1/2b+ 4 = 9.5

C. -3b + 5 = -38

D. -40 = 5b + 15

C does not have the solution b = 11

400

What is the second step?

-2+1/7p=-4

Multiply both sides by 7
