Question

46+y:5=85 49+(136-x*8):4=81

Answer 1

Пошаговое объяснение:

$46 + y \div 5 = 85 \\ 46 + \frac{y}{5} = 8 \\ 230 + \frac{y}{5} = 425 \\ \frac{y}{5}= 425 - 230 \\ \frac{y}{5} = 195$

у=195*5;

у=975.

$49 + (136 - x \times 8) \div 4 = 81 \\ 49 + \frac{136}{4} - \frac{8x}{4} = 81 \\ 49 + 34 - 2x = 81 \\ - 2x = 81 - 49 - 34 \\ - 2x = - 2 \\ x = 1$

Answer 2

To solve the equations, let's find the value of the variable "y" in the first equation and the value of the variable "x" in the second equation:

1. 46 + y ÷ 5 = 85

To isolate "y" on one side, we'll first get rid of the constant term on the left side:

46 + y ÷ 5 - 46 = 85 - 46 y ÷ 5 = 39

Now, we'll get "y" by itself by multiplying both sides by 5:

y = 39 × 5 y = 195

So, the value of "y" is 195.

2. 49 + (136 - x * 8) ÷ 4 = 81

Let's start by simplifying the expression inside the parentheses:

136 - x * 8 = 136 - 8x

Now, the equation becomes:

49 + (136 - 8x) ÷ 4 = 81

Next, let's get rid of the constant term on the left side:

49 + (136 - 8x) ÷ 4 - 49 = 81 - 49 (136 - 8x) ÷ 4 = 32

Now, we'll isolate "x" on one side by multiplying both sides by 4:

4 × [(136 - 8x) ÷ 4] = 4 × 32 136 - 8x = 128

To solve for "x," we'll move the constant term to the other side:

-8x = 128 - 136 -8x = -8

Finally, divide both sides by -8:

x = -8 ÷ -8 x = 1

So, the value of "x" is 1.

Therefore, the solutions to the equations are: y = 195 x = 1
