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 = [tex]\frac{-11}{4}[/tex]
Step-by-step explanation:
Answer:
x = -11/4
Step-by-step 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
