Solve for y : 3x+5y=10

3x+5y=10

how to solve for 3x-5y = 9

where; x = - 1, 0, 1

(x=-1, y = - 2.4); (x=0, y = - 1.8) (x=1, y = - 1.2)

in x = - 1 in x = 0 in x = 1

3 (-1) - 5y = 9 3 (0) - 5y = 9 3 (1) - 5y = 9

-3-5y = 9 - 5y = 9 3-5y = 9

-5y = 9+3 - 5 - 5 5y = 9-3

-5y = 12 (cancel - 5) 5y = 6

-5 - 5 y = - 1.8 5 - 5

(cancel - 5) (cancel - 5)

y = - 2.4 y = - 1.

3x + 5y = 10 Subtract 3x from both sides. 5y = - 3x + 10 Divide both sides by 5. y = - 3/5x + 2
