Question

determine if (1/2, -4) is a solution to 4x-3y=10

Answer 1

Plug in x = 1/2 and y = -4

Then evaluate/simplify

If you get a true equation, then (1/2, -4) is a solution

Answer 2

substitute them both to see if the solution is 10

4(1/2) - 3(-4) = ??

if its 10 then the ordered pair is a solution

Answer 3

how do you get 12

Answer 4

4*1/2-(3*-4) =(2+12) =14....sry lhs 14...calculation mistake!

Answer 5

got it thank you
