Question

for graph drawing

2x+y =-4 if y=-2
what is the value of x
​

Answer 1

2x + y = - 4

At y = - 2

2x - 2 = - 4

2x = - 4 + 2

2x = - 2

x = - 2/2

x = - 1 ➡ Answer

Answer 2

Given,

(2x+y) = -4

y = -2

To find,

The value of x.

Solution,

The value of x will be -1.

We can easily solve this problem by following the given steps.

According to the question,

(2x+y) = -4

Putting the value of y in this above equation,

2x-2 = -4

2x = -4+2 (Moving 2 from the left-hand side to the right-hand side results in the change of sign from minus to plus.)

2x = -2

x = -2/2 (2 was in the multiplication on the left-hand side. So, it is in the division on the right-hand side.)

x = -1

(Note that you can point these values of x and y on the graph and join these points through a straight line.)

Hence, the value of x is -1.
