Solve the following equation: -15c+7c+1=3-8c

Add -15c and 7c since they have the same variable. After that you get a negative answer so you add the answer to both sides. That will cancel both numbers so it will be 1=3, the answer will be false.

Add like terms
-15c+7c=7c-15c=-8c
we can't add the c terms and the numbers so we leave it so
-8c+1=3-8c
add 8c to both sides
8c-8c+1=3+8c-8c
0+1=3+0
1=3
false
there is no solution

Solve the absolute value equation. 4|4x - 3| - 8 = -4

soldier1979 [14.2K]

Answer:

x = $1,\frac{1}{2}$

Step-by-step explanation:

$4|4x-3|-8=-4\\$

Add 8 to both sides;

4|4x - 3| = 4 4|4x - 3| = -4

Divide both sides by 4;

4x - 3 = 1 4x - 3 = -1

Add 3 to both sides;

4x = 4 4x = 2

Divide both sides by 4;

x = 1 x = $\frac{1}{2}$

Answer: the price for an adult ticket is $3

Step-by-step explanation:

Let x represent the price of one adult ticket.

Let y represent the price of one child ticket.

The Martinez family went to play and paid $13 for 1 adult and 4 children. This means that

x + 4y = 13 - - - - - - - - - - -1

The Hernandez family went to the same place and paid $14 for 3 adults and 2 children. This means that

3x + 2y = 14 - - - -- - - - - - - -2

Multiplying equation 1 by 3 and equation 3 by 1, it becomes

3x + 12y = 39

3x + 2y = 14

Subtracting, it becomes

10y = 25

y = 25/10 = 2.5

Substituting y = 2.5 into equation 1, it becomes

x + 4 × 2.5 = 13

x + 10 = 13

x = 13 - 10

x = 3
