-4x + 7 = -21

whats x AHSAJ I NEEDD HELPPP

-4x+7= -21

-4x= -21-7( this positive 7 will change to negative as we take in other side )

-4x = -28

Both the negative will be cancelled

4x = 28

x = 28/4

X = 7

therefore the X value is 7

- 4x+7=-21

-4x=-21-7

-4x=-28

x=7

Step-by-step explanation:

Like terms are collected first

The +7 moves to the other side of the equality sign making its sign negative (-7)

Two negatives makes a positive but the sign remains negative (when you have two numbers with a negative sign you sum them up but the sign of the sum remains negative)

Then divide both side by the coefficient of x which is - 4

-4x/4 =-28/4

The negative signs cancel out

x=7
