Solve the system by the addition method <br> 4x=3y-8<br> -16x+4y=32
butalik [34]
4x = 3y - 8
 4         4
  x = ³/₄y - 2

                  -16x + 4y = 32
       -16(³/₄y - 2) + 4y = 32
-16(³/₄y) + 16(2) + 4y = 32
          -12y + 32 + 4y = 32
          -12y + 4y + 32 = 32
                    -8y + 32 = 32
                           - 32  - 32
                            -8y = 0
                             -8    -8
                               y = 0
x = ³/₄y - 2
x = ³/₄(0) - 2
x = 0 - 2
x = -2

(x, y) = (-2, 0)

Need the steps too this

The value of x  is 9.

We have :    - 25 = 7 - (5x - 13)

We have to find the value of x.

<h3>If f(x) = g(x), than what do you understand by true solution of this equation?</h3>

The true Solution of the equation is the value of x for which LHS = RHS.

For example - if  ax + b = cx + d , then

ax - cx = d - b

x = \frac{d-b}{a-c}   is the true solution of the equation.

In the question given -

- 25 = 7 - (5x - 13)

- 25 = 7 - 5x + 13

5x = 45

x = 9

Hence, the value of x for which LHS = RHS is 9.

A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the
trapecia [35]
1999 price = 11900
it depreciates 13%
\frac{13}{100} \times 11900 = 1547
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
\frac{13}{100} \times 10353 = 1345.89
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
\frac{13}{100} \times 9007.11 = 1170.92
year 2002 cost = 9007.11 - 1170.92 = 7836.19
