Question

240 :( x+3)-5=7

Answer 1

240:(х+3)=7+5

х+3=240:12

х+3=20

х=20-3 =17

Answer 2

240:(x+3)-5=7

240:(x+3)=5+7

240:(x+3)=12

x+3=240:12

x+3=20
x=20-3

x=17

Проверка:

240:(17+3)-5=7

12-5=7

7=7

Answer 3

To solve the equation, let's go step by step:

240(x + 3) - 5 = 7

First, we distribute the 240 to the terms inside the parentheses:

240x + 720 - 5 = 7

Combine like terms:

240x + 715 = 7

Next, isolate the term with the variable by subtracting 715 from both sides:

240x = 7 - 715

240x = -708

Finally, divide both sides by 240 to solve for x:

x = -708/240

Simplifying the fraction:

x = -59/20

Therefore, the solution to the equation is x = -59/20.
