How to solve 9x+5=28

-3x-10y=-26 by Elimination

So elimination

I assume that you meant to write

9x+5y=28 and not 9x+5=28

so

elimination is basically eliminating values

9x+5y=28

-3x-10y=-26

we can either cancel out the x terms or the y terms, I will cancel out the y terms

9x+5y=28

multipy both sides by 2

18x+10y=56

add to other equation

18x+10y=56

-3x-10y=-26 +

15x+0y=30

15x=30

divide both sides by 15

x=2

subsitute

9x+5y=28

9 (2) + 5y=28

18+5y=28

subtract 10 from both sides

5y=10

divide both sides by 5

y=2

x=2

y=2

9x + 5 = 28

- 5 - 5

9x = 23

9 9

x = 2⁵/₉

-3 (2⁵/₉) - 10y = - 26

-7²/₃ - 10y = - 26

+ 7²/₃ + 7²/₃

-10y = - 18¹/₃

-10 - 10

y = 1⁵/₆

(x, y) = (2⁵/₉, 1⁵/₆)
