What is the simplified form of this expression
3x+4+5x+3

• 15x

• 8x+7

• 7x+8

Add these expressions
(3x+15) + (4x+13)

• 7x+ 28

• 35x

• x+2

6z + 3 -4z = 9

• z = 3

• z = 60

• z = 30

• z = 1

Solve 
  -5t + 9 = 24

• t = -3

• t = 3

• t = 6

• t = 12

3x + 2(4x - 4) = 3

• x = 22

• x = -22

• x = 1

• x = -1

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

Evaluate the expression.    Let     c = 3     d = 2
3c + 7d

• 27

• 21

• 29

• 23

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

• Subtract 11 from both sides

• Divide  - 3 on both sides

• Add 3 to both sides

• Add 11 to both sides

-6(8x-7)=522

• x=-10

• x=109

• x=10

• x=4

Evaluate the expression (4³ - 4) + 12 ÷ 3

• 64

• 12

• 24

• 6.6
