3. Solve using substitution.<br> x - y = 4<br> 3x - 2y = -5

Vedmedyk [2.9K]

<u>Given</u>:

The system of linear equations are $x-y=4$ and $3x-2y=-5$

We need to determine the solution to the system of equations using substitution method.

<u>Solution</u>:

The solution can be determined using the substitution method.

Let us substitute $x=4+y$ in the equation $3x-2y=-5$

Thus, we have;

$3(4+y)-2y=-5$

$12+3y-2y=-5$

$12+y=-5$

$y=-17$

Thus, the value of y is -17.

Substituting $y=-17$ in the equation $x-y=4$ , we get;

$x+17=4$

$x=-13$

Thus, the value of x is -13.

Hence, the solution to the system of equations is (-13,-17)

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. H

lidiya [134]

Answer: There were 7 children

Step-by-step explanation:

Let's use <em>x </em>to represent the children and <em>y </em>to represent the adults.

We know they combine to make a group of 25 people so x+y=25

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201

I will solve by substitution.

Solve for y in the first equation

$x+y=25\\x-x+y=25-x\\y=25-x$

Sub in our value for y into the other equation and solve for x

$3x+10y=201\\3x+10(25-x)=201$

Step 1) Simplify

$3x+250-10x=201\\-7x+250=201$

Step 2) Subtract 250 from both sides

$-7x+250-250=201-250\\-7x=-49$

Step 3) Divide both sides by -7

$\frac{-7x}{-7} =\frac{-49}{-7}\\x=7$
