Question

Determine the missing coordinate in the orderd pair (?,-3) so that it will satisfy the given equation. Answer: (______,-3). consider the following equation.4x+3y=7

Answer 1

if we replace y for -3 in the given equation and then we despejate x, we wiil going to have a values for the ordered pair that satisfy the equation:

`4x+3(-3)=7`

then

`4x-9=7\Rightarrow4x=7+9\Rightarrow4x=16\Rightarrow x=(16)/(4)=4`

the ordered pair woul be (4,-3)
