Question

15*(с-8х)=75при с =53

Answer 1

15×(с-8х)=75 при с=53
15с-120х=75
120х=75-15с
120х=75-15×53
120х=75-795
120х=-720
х=-6

Answer 2

15*(с-8х)=75 при с=53
15*(53-8х)=75
795-120х=75
-120х=795-75
-120х=720
х=720:120
х=6

Answer 3

To solve this equation, we substitute c = 53 into the equation and then solve for x:

15*(c - 8x) = 75 (substitute c = 53) 15*(53 - 8x) = 75 795 - 120x = 75 (multiply out the brackets) -120x = -720 x = 6

Therefore, the solution to the equation 15*(c - 8x) = 75 when c = 53 is x = 6.
