Answer:

x = -11/4

Explanation:

First we collect liked terms:

x - 4 = 5x + 7

Subtract 5x from both sides

-4x - 4 = 7

Add 4 to both sides

-4x = 11

Divide both sides by -4

x = -11/4

Answer:

Since you are to calculate the value of x, the first thing to do is to collect the like terms, i.e bring all the families of x together.

which implies : x -12x +7x = 7 + 4

-4x = 11

Divide both sides by -4

therefore : x =
(-11)/(4)
