7x-8,3x-41,5=4,4+3x
Use the distributive property to multiply -8,3 by x+5.
-1,3x-41,5=4,4+3x
Combine 7x and -8,3x to get -1,3x.
-1,3x-41,5-3x=4,4
Subtract 3x from both sides.
-4,3x-41,5=4,4
Combine -1,3x and -3x to get -4,3x.
-4,3x=4,4+41,5
Add 41,5 to both sides.
-4,3x=45,9
Add 4,4 and 41,5 to get 45,9.
x=\frac{45,9}{-4,3}
Divide both sides by -4,3.
x=\frac{459}{-43}
Expand \frac{45,9}{-4,3} by multiplying both numerator and the denominator by 10.
x=-\frac{459}{43}
Fraction \frac{459}{-43} can be rewritten as -\frac{459}{43} by extracting the negative sign.
