5x147x54 solve for xSolution5x1 4 7x5 4 we have to distribu

5(x+1)+4=7(x5)4 solve for x

Solution

5(x+1) + 4= 7(x5) 4

we have to distribute \"5\" over (x+1) so we get 5x + 5.

5x + 5 + 4 = -7(x-5) -4

similarly we have to distribute \"-7\" over (x - 5).

so we multiply -7and (x-5) we get -7*x -7*(-5)

-7x + 35           

(we multiply \"-7\" and \"x\" we get -7x) (positive number * negative number = negative number)                                          (  \"-7\" * \"-5\" = -7*-5 = 35 ) (negative number * negative number = positive number)

5x +5 +4 = -7x + 35 -4

5x + 9 = -7x + 31

5x + 7x +9 = -7x +7x +31   ( we add \"7x\" both sides)

12x + 9 = 31

12x +9 -9 = 31 - 9                  (we subtract \"9\" both sides)

12x = 22

x = 22/12                        (we divide both sides by \"12\")

x = 11/6
