Question

320 - ( y * 4+ 120):5= 240​

Answer 1

Ответ:

320-(4y+120):5=240

320-4y:5-24=240

296-4y:5=240

4y:5=296-240

4y:5=56

4y=5*56

4y=280

y=280:4

y=70

Answer 2

Let's solve the equation step by step:

320 - (y * 4 + 120) / 5 = 240

First, simplify the expression inside the parentheses:

320 - (4y + 120) / 5 = 240

Now, distribute the division by 5 to both terms inside the parentheses:

320 - (4y / 5 + 120 / 5) = 240

Simplify further:

320 - (0.8y + 24) = 240

Now, subtract 320 from both sides of the equation:

-0.8y - 24 = -80

Next, add 24 to both sides:

-0.8y = -56

Finally, divide both sides by -0.8 to solve for y:

y = -56 / -0.8 y = 70

So, the solution to the equation is y = 70.
