First you can add 50 dollars to 450 dollars which is 500 then divide that 500 by 2 and that is 250

Answer:

$450+$50= X

X=$500

Step-by-step explanation:

The sale price is $450.00, so you take that amount and $50.00 which the amount he paid less and add them both. We do this because we want to see the original price of the computer. If it mentioned the original price already and the amount $50.00 and asked the sail price instead, we would have to subtract to get the answer.

Here we have to add.

450+50=500

(add the dollar sign)

$450+$50=X

X=$500

Solve using substitution x=(3y+1) and x+4y=15
natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2

Putting x = 3y+1 in equation 2 from equation 1

3y+1+4y = 15\\7y+1 = 15\\

Subtracting 1 from both sides

7y+1-1 = 15-1\\7y = 14

Dividing both sides by 7

\frac{7y}{7} =\frac{14}{7}\\y = 2

Putting y=2 in equation 1

x = 3(2) +1\\x = 6+1\\x = 7

Hence,

The solution is: x= 7 and y = 2

What is the first step to solve the following system of equations using substitution?
Akimi4 [234]

Answer:

Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

Thus, option A) is true.

The solution to the system of equations be:

x = 4, y = 5

Step-by-step explanation:

It is important to remember that when we solve the system of equations, the first step we need to do is to solve one of the equations for one of the variables.

Given the system of equations

x - y = -1

2x - y = 3

Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x

x-y=-1

Add y to both sides

x-y+y=-1+y

x=-1+y

Thus, option A) is true.

<u>NOW LET US SOLVE THE REMAINING PORTION</u>

\mathrm{Subsititute\:}x=-1+y to solve for y

\begin{bmatrix}2\left(-1+y\right)-y=3\end{bmatrix}

-2+y=3

y=5

For x = -1 + y

substitute y = 5

x=-1+5

x=4

Thus, the solution to the system of equations be:

x = 4, y = 5
