Please find the X and Y plot points!! (I’ll give brainliest: x+2y=10 -x+y=2

Step-by-step explanation:

x+2y = 10 ...1

-x+y = 2 ...2

...1 + ...2

x+2y+(-x+y) = 10 + 2

3y = 12

y = 12/3

= 4

Replace y = 4 in ...1

x + 2(4) = 10

x + 8 = 10

x = 10 - 8

= 2

(x,y) = (2,4)

(- 6, 8 )

Step-by-step explanation:

Given the 2 equations

x + 2y = 10 → (1)

x + y = 2 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 10 - 2y → (3)

Substitute x = 10 - 2y into (2)

10 - 2y + y = 2

10 - y = 2 ( subtract 10 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8

Substitute y = 8 into (3) for corresponding value of x

x = 10 - 2(8) = 10 - 16 = - 6

solution is (- 6, 8 )

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
