Is It a Solution to an Equation

Solve:
5y + 34 = -2(-7y+1)

• y = -4

• y = 9

• y = 4

• y = 36/19

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

• x = -8

• x = 8

• x = 2

• x = -2

The value of the variable that makes an equation true is the

• solution

• coefficient

• constant

• unknown

When x = 6 in the equation
3x = 18
3(6) = 18
18= 18
TRUE OR FALSE?

• TRUE

• FALSE

Tell whether the value of the variable is a solution to the equation:

3x=12; x=4

• yes

• no

Tell whether the value of the variable is a solution to the equation:

7 = 13 - n; n=5

• Yes

• No

• yes

• no

To "satisfy" an equation means to

• make it true

• simplify it

• repair it

• make it smile

Which equation has w = 8 as the solution?

• 8w= 64

• 16w = 240

• 16 - w = 9

• 4 + w = 10

When x = 12 in the equation
3a - 14 = 22 
3(  ) - 14 = 22
IS IT TRUE OR FALSE?

• TRUE

• FALSE
