Question

720:(y:7+80)=6 115-6×x=73

Answer 1

Просто переписываешь, надеюсь понятно.

Answer 2

To solve the equations:

1. 720 ÷ (y + 7 + 80) = 6

First, let's simplify the equation by combining like terms:

720 ÷ (y + 87) = 6

Next, we can cross-multiply to solve for y:

720 = 6 * (y + 87)

720 = 6y + 522

Subtract 522 from both sides:

720 - 522 = 6y

198 = 6y

Divide both sides by 6:

198 ÷ 6 = y

y = 33

Therefore, the solution for the first equation is y = 33.

2. 115 - 6x = 73

Let's isolate the variable x by performing the necessary operations:

Subtract 115 from both sides:

115 - 115 - 6x = 73 - 115

-6x = -42

Divide both sides by -6:

-6x ÷ -6 = -42 ÷ -6

x = 7

Therefore, the solution for the second equation is x = 7.

In summary: The solution for the first equation is y = 33. The solution for the second equation is x = 7.
