Which system of equations has the solution (4,−2)?

Marat540 [252]

Answer:

Step-by-step explanation:

To find the answer we must solve each of the systems separately. Starting with the first one:

x + y = 2

2x - y = 10

We must find what x or y is equal to and then replace it in the second equation. I'll go with y as it seems easier:

x + y = 2

y = 2 - x

Now that we found y we replace it in the second equation this way. Be careful with the signs, the minus with change our signs:

2x - (2 - x) = 10

2x - 2 + x = 10

3x = 12

x = 12/3

x = 4

Now that we have x, we replace the variable with its value in one of the equations. Again, for simplicity I'll go with the one that seems easier.

4 + y = 2

y = 2 - 4

y = - 2

PLEASE FOLLOW THE DIRECTIONS AND SHOW YOUR WORK. IM OFFERING 15PTS (Way more than its worth) AND BRAINLIEST ANSWER. PLEASE HELP

Alex

I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.

a. $x+y=425, x-y=25$

b. I will solve your system using substitution.
$x+y-425, x-y=25$
Step 1: Solve $x+y=425$ for x
$x+y+-y=425+-y$ (add -y for both sides)
$x=-y+425$
Step 2: substitute $-y+425$ for x in $x+b=25$
$x+y=25$
 $-y+425-y=25$
$-2y+425=25$ (simplify both sides of the equation)
$-2y+425+-425=25+-425$ (add -425 to both sides)
 $-2y=-400$
$\frac{-2y}{-2} = \frac{-400}{-2}$
y=200
step 3: substitute 200 for y in $x=-y+425$
$x=-y+425$
$x=-200+425
$
$x=225$
$x=225, y= 200$

c. Already answered with the picture that is attached.

d. Gavin earned 225 dollars while Seiji earned 200 dollars.
