Question

Help.Solve 5x + 3 = -7

A. -2

B. -0.8


c. 2

D.-20​

Answer 1

5x + 3 = -7

move -3 to the other side

sign changes from -3 to +3

5x+3-3= -7-3

5x= -10

divide both sides by 5 to get x by itself

5x/5= -10/5

cross out 5 and 5, divide by 5 and then becomes 1*1*x= x

x= -10/5

x= -2

answer:

A. -2

Answer 2

The answer Is A -2 :)
