Question

1)y-286=342×2. 2)x+278=600+329. 3)180÷x=135÷5. 4)900-y=5+4-196

Answer 1

Ответ:

у это 970

2)651

3) наверное 6.6

4)187

Answer 2

Let's solve each of the equations step by step:

1. y - 286 = 342 × 2

To solve for y, we'll start by simplifying the right side of the equation: y - 286 = 684

Next, we'll isolate y by adding 286 to both sides of the equation: y = 684 + 286 y = 970

So the solution to the equation is y = 970.

2. x + 278 = 600 + 329

To solve for x, we'll start by simplifying the right side of the equation: x + 278 = 929

Next, we'll isolate x by subtracting 278 from both sides of the equation: x = 929 - 278 x = 651

So the solution to the equation is x = 651.

3. 180 ÷ x = 135 ÷ 5

To solve for x, we'll cross-multiply: 5 × 180 = 135 × x

Simplifying both sides: 900 = 135x

To isolate x, we'll divide both sides of the equation by 135: 900 ÷ 135 = x x = 6

So the solution to the equation is x = 6.

4. 900 - y = 5 + 4 - 196

To solve for y, we'll simplify the right side of the equation: 900 - y = 9 - 196

Simplifying further: 900 - y = -187

To isolate y, we'll subtract 900 from both sides of the equation: -y = -187 - 900 -y = -1087

Finally, we'll multiply both sides of the equation by -1 to solve for y: y = 1087

So the solution to the equation is y = 1087.
