subtract 64^× from both sides of the equation
16x -64×=4
Since it is true that 9=9, the answer x=2 works.
As equations get more complex it is important to use properties of equality to isolate the variable and solve the equation.
Here are the properties of equality you need to isolate terms and solve equations.
The Subtraction Property of Equality is used when you have an equation with addition in it. It states that you can subtract the same quantity from both sides of the equation without changing the equality.
The Addition Property of Equality is used when you have an equation with subtraction in it. It states that you can add the same quantity to both sides of the equation without changing the equality.
The Division Property of Equality is used when you have an equation with a variable multiplied by a number. It states that you can divide both sides of an equation by the same quantity (as long as that quantity is not equal to zero) without changing the equality.
The Multiplication Property of Equality is used when you have an equation with a variable divided by a number. It states that you can multiply both sides of an equation by the same quantity without changing the equality.
Let’s look at an example and use properties of equality to isolate the variable and solve the equation.

Answer:
170
Step-by-step explanation:
Given
Tickets = $2 per single and $3 per couple
Total tickets = 365
Total receipts = $925
Required
Number of singles tickets sold.
Let S and C represent singles and couples respectively.
If the total number of tickets sold is 365, then
S + C = 365 --- (1)
Also, if the singles are charged $2 and couples, $3, then
2S + 3C = 925 ----- (2)
Make C the subject of formula in (1)
C = 365 - S
Substitute 365 - S for C in (2)
2S + 3(365 - S) = 925
Open bracket
2S + 1095 - 3S = 925
Collect like terms
2S - 3S = 925 - 1095
-S = -170
Multiply both sides by -1
-1 * -S = -1 * -170
S = 170
Recall that S represents number of single present at the even.
Hence, the number of singles are 170
4 - (x + 2) < -3(x + 4)
4 - x - 2 < -3(x) - 3(4)
4 - x - 2 < -3x - 12
-x + 2 < -3x - 12
2x + 2 < -12
2x < -14
x < -7
The answer is A.
6.32 is the final answer! :)
