Intro to Algebra - Solving Equations - Multiple Choice Section

2x + 3(5x - 7) = 47

• x = 1

• x = 2

• x = 3

• x = 4

Solve the equation
-8x - 8 +3(x - 2) = -3x + 2

• x = -8

• x = 8

• x = 2

• x = -2

How many solutions?

2(3x-4)-6x=-4

• One

• Two

• Infinite

• None

3y+6+4y-7=-8

• y=-1

• y=-8

• y=1

• y=7

Solve:
2(4x-3) - 8 = 4 + 2x

• x = 5/3

• x = 3

• x = 1

• x = 2

4x-2x+ 5= 24 - 2x + 5 -8x

• 1

• 2

• 3

• 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

12(2k + 11) = 12(2k + 12)

• 144

• -12

• no solution

• all real numbers

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

 $-118=-5\left(4+7x\right)+7$  

•  $-5$  

•  $-9$  

•  $3$  

•  $-1$
