x+6=9

Subtract 6 from 9.

x=3

3b+4=19

3b=23

b= 23/3

They added 4 instead of subtracting

100
2x+5= 3x
x=5
100

8(x-2)=6x

x=8

Name the three different types of solutions for equations.
One solution, No solution, infinite solutions
200

-2x -8= -32

Add 8 on both sides

-2x=-24

An equation has one solution if ____________

The coefficients (bodyguards) are different

300

3(m-2)= -19

Distribute 3 to (m-2)

3m-6= -19

300

-5y+7= -23

5y=-30

y=-6

They dropped their negatives/divided by a +5 instead of -5

300
5x+2= 3x-8
x=-5
300
-(a-12)+4a= 9a
a=2
300
If after solving the equation you arrive at 5 = -5, what is the type of solution?
No solution
400

(3/4)h +3 = -3

(3/4)h = -6

Clear the fraction by multiplying by 4 {3h=-24}

or

Divide by 3/4 by multiplying by the reciprocal (4/3) {h=-8}


400

4(x-8)= -16

4x-8=-16

4x=-8

They didn't distribute correctly and multiply 4 times 8.

400
16-4x=7x+5
x=1

-5(2x-3)= 12-x

-10x + 15 = 12 - x


Move variables all to one side and combine like terms

-10x +x = 12 -15

-9x = -3

500

4/5 m +2= -6

4/5m=-4

m=-5

They did not subtract -6 -2 correctly/Added 2 instead of subtracting 2.

500

4(2a+3)= -3(a-1)+33

a=3

4n-1= 6n+8-8n+15

a=4
