To find this answer you need to try to plug in the x and y values into the equations and see which one solves both equations.
First lets plug in the point (1,-1) into the first equation x - 2y = 3
1 - 2(-1) = 3
1+ 2 = 3 This works here lets try the other equation

5x + 3y = 2
5(1) + 3 (-1) = 2
5 - 3 = 2 This works as well so this is your answer

Solve the system algebraically. 2x+ y - 10 = 0 x - y - 4 = 0 What is the value of y? 1/3 2/3 14/3
Weegy: Adding both equations gives us 3x=14; Therefore x=14/3. Substituting this value to the second equation gives: (14/3)-y=4; Grouping similar terms: (14/3)-4=y; (14/3)-(12/3)=y;y Therefore is 2/3 (More)

2x+ y - 10 = 0 x - y - 4 = 0 What is the value of y? 1/3 2/3 14/3

To solve for y subtract the 2 equations

2x + y - 10 = 0
-x + y + 4 = 0
Answer is x + 2y - 6 = 0

get numbers on one side so x + 2y = 6

to solve for y we need it on a side by itself so we need to subtract x from both sides. When we do this we have 2y = -x + 6.

Now we divide both sides by 2 to isolate the y.

y = -x/2 + 3 This is the answer

Solve the system algebraically. Check your work. 5x + 2y = 10 3x + 2y = 6
Weegy: 5x+2y=10_3x+2y=6 Since 2y does not contain the variable to solve for, [ move it to the right-hand side of the equation by subtracting 2y from both sides. 5x=-2y+10_3x+2y=6 Divide each term in the equation by 5. x=-(2(y-5))/(5)_3x+2y=6 Since the equation was solved for x, replace all occurrences of x in the other equations with the solution (-(2(y-5))/(5)). x=-(2(y-5))/(5)_3(-(2(y-5))/(5))+2y=6 Multiply -2 by each term inside the ...

5x + 2y = 10 3x + 2y = 6 I would subtract the two equations thus you would have
5x + 2y =10
-3x - 2y = -6

The 2y would cancel out so you have 2x =4 divide both by 2 and you get x = 2.

Choose an equation and plug in a 2 for x for the first one you get 5(2) + 2y = 10
10 + 2y = 10
y = 0

Now to check try both numbers in the second equation to see if we are correct
3x +2y = 6
3(2) + 2(0) = 6
6 + 0 = 6
6 = 6

Your answer is (2,0)

(3x+5)+(2x-9)-(4x-3)=x-7

3x +5+2x-9-4x-3=x-7
=x-7=x-7
collect the like terms.
x-x=-7+7
x=0.
