Question

(24-y)*5-32=48. 720:(c:7+80)=6

Answer 1

(24-у)*5-32=48
(24-у)*5=48+32
(24-у)*5=80
24-у=80:5
24-у=16
у=24-16
у=8

Ответ: с=280

Answer 3

Let's solve each equation step by step:

1. $(24 - y) \cdot 5 - 32 = 48$

First, simplify the equation:

$(24 - y) \cdot 5 - 32 = 48$

Now, distribute the 5 on the left side:

$5(24 - y) - 32 = 48$

Next, multiply 5 by each term inside the parentheses:

$120 - 5y - 32 = 48$

Now, combine like terms by adding 32 to both sides:

$120 - 5y - 32 + 32 = 48 + 32$

Simplify:

$120 - 5y = 80$

Now, isolate the variable $y$ by subtracting 120 from both sides:

$120 - 120 - 5y = 80 - 120$

Simplify:

$-5y = -40$

Now, divide both sides by -5 to solve for $y$:

$\frac{-5y}{-5} = \frac{-40}{-5}$

Simplify:

$y = 8$

So, the solution to the first equation is $y = 8$.

2. $\frac{720}{c:7 + 80} = 6$

First, simplify the expression inside the parentheses:

$c:7 + 80 = 6$

Now, subtract 80 from both sides:

$c:7 = 6 - 80$

Simplify:

$c:7 = -74$

To solve for $c$, multiply both sides by 7:

$7(c:7) = -74 \cdot 7$

Simplify:

$c = -518$

So, the solution to the second equation is $c = -518$.
