Question

. Which of the following are solutions of the equation 4x+3y=-12?
(a) (5, 1)
(b) (0,4)
(C) (0-4)
(d) (-4,0)
​

Answer 1

only (0,-4) is the solution of the equation

Answer 2

$\huge \mathtt{\red{A}\pink{n}\blue{s}\purple{w}\green{e}\pink{r}}$

4x+3y= -12

4x= -12 -3y------(i)

Now put 4x= -12-3y

4x+3y= -12

-12 -3y +3y= -12

-12= -12

$- 12 + 12 = 0$

So x=0

Put the value of x in 4x+3y= -12

4×0+3y=12

0+3y=12

$y = \frac{12}{3} = 4$

So y=4

So your answer is (b) 0,4
