Answer 1

Ответ:

Пошаговое объяснение:

35+x=200-140

35+x=200+140

35+x=340

x=340-35

x=305

35+305=200-140

a-(47+33)=310+210

a-(47+33)=520

a=47+33

a=80

a=520+80

a=600

600-(47+33)=310+210

y+230=9*4+640

y+230=676

y=676-230

y=446

446+230=9*4+640

Answer 2

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

1. 35 + x = 200 - 140

To solve for x, we'll first combine the numbers on the right side and then isolate x on one side of the equation.

Step 1: Simplify the right side of the equation: 200 - 140 = 60

Step 2: Rewrite the equation with the simplified right side: 35 + x = 60

Step 3: Isolate x on one side by subtracting 35 from both sides of the equation: 35 - 35 + x = 60 - 35

Simplified: x = 25

So, the value of x is 25.

2. a - (47 + 33) = 310 + 210

To solve for a, we'll follow similar steps:

Step 1: Simplify the left side of the equation: a - (47 + 33) = a - 80

Step 2: Simplify the right side of the equation: 310 + 210 = 520

Step 3: Rewrite the equation with the simplified expressions: a - 80 = 520

Step 4: Isolate a on one side by adding 80 to both sides of the equation: a - 80 + 80 = 520 + 80

Simplified: a = 600

So, the value of a is 600.

3. y + 230 = 9 * 4 + 640

To solve for y, follow these steps:

Step 1: Simplify the right side of the equation: 9 * 4 = 36 36 + 640 = 676

Step 2: Rewrite the equation with the simplified right side: y + 230 = 676

Step 3: Isolate y on one side by subtracting 230 from both sides of the equation: y + 230 - 230 = 676 - 230

Simplified: y = 446

So, the value of y is 446.

Final results: x = 25 a = 600 y = 446
