We need to find the value of
2x-7 and the value of x=-1
It’s known that we have to multiply the variable x with 2, and the value of variable x is -1…then,
2x-7,in the place of x we need to put -1 and multiply it.
=2(-1)-7
= -2 -7. (The value of 2×-1is -2)
= -9 ( the value of -2-7 is -9)……the problem is solved….

-2x-7 [x= -1]

=-2-7

=-9

2x-7 and the value of x=-1

[2 x -1] -7

-2 -7

If same sign comes, find their sum and put the same sign.

So we get -[2+7] = -9

-9 is the value of 2x-7 when x=-1

-9

2*x-7 where x=-1

2*(-1)-7=-2-7=-9

hope it will be helpful

2x-7 [x=1]

2*1-7= -5
