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
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
therefore : x =
the equation would be n-5/7
the division side should be long though because I can't insert it
now one denominator is x^2 + 8x + 15 if we factorise then (x +3)(x +5) now in expressions which have like x+3 as denominator ...you multiply and divide them by x+5 and once u get denominator equal you can add numerator easily
