Multi-step Equations

Which is the first step in simplifying 2(3x - 1) = 5x -3 ?

• 5x - 2 = 5x - 3

• 6x - 1 = 5x - 3

• 6x - 2 = 5x - 3

• 5x - 1 = 5x - 3

The first step in simplifying

 $\frac{1}{2}\left(\ 6x\ +\ 8\right)\ =\ 2x\ +\ 10$  ?

• 12x + 16 = 2x + 10

• 3x + 4 = 2x + 10

• 4x + 6 = 2x + 10

• 3x + 8 = 2x + 10

Which will you apply first to solve 2x - 5 = x + 7 ?

• add x on both sides

• add 7 on both sides

• divide all by 2

• add 5 on both sides

Which step is wrong in simplifying 12x - 18 = 13x + 18 ?

• 12x - 13x = 18 + 18

• -x = 36

• $\frac{-x}{1}\ =\ \frac{36}{1}$

• x = -36

• $\frac{-x}{-1}=\frac{36}{-1}$

Which is the second step in simplifying 4 (y - 6) = - 4 ?

• $\frac{4y}{4}=\ \frac{20}{4}$

• 4y - 24 + 24 = - 4 + 24

• 4y = 20

• 4y - 24 = - 4

Which is the first step in simplifying 5(m - 2) = 3(m + 4) ?

• 5m - 2 = 3m + 4

• 5m - 10 = 3m + 12

• 5m + 10 = 3m + 12

• 5m - 10 = 3m - 12

Which is the second step in simplifying

 $\frac{1}{2}\ \left(\ 8m\ +\ 4\right)\ =\ 3m\ +\ 6\ ?$  

• 4m - 3m = 2 + 6

• 4m + 3m = -2 + 6

• 4m + 2 = 3m + 6

• 4m - 3m = -2 + 6

What is the first step in simplifying

 $\frac{1}{3}\left(\ 9x\ +\ 6\right)\ =\ \frac{1}{2}\left(\ 4x\ +\ 8\right)\ ?$  

• 3x - 2 = 2x + 6

• 3x + 2 = 2x + 4

• 3x + 3 = 2x + 6

• 3x + 2 = 2x - 4

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a

• Distribute 4 to a and -5

• Distribute -4 to a and -5

What is the first step in solving this equation? 
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7
