Answer 1

Ответ:

Пошаговое объяснение:

696-x=114+126

696-х=240

-х=240-696

-х=-456

Х=456

x+150=800-440

Х+150=360

Х=360-150

Х=210

560+b=980-140

560+b=840

b=840-560

b=280

Answer 2

Let's solve each equation step by step:

1. 696 - x = 114 + 126 To solve for x, first, we need to simplify the equation by combining like terms: 696 - x = 240

Next, isolate x by moving the constants to the other side of the equation: -x = 240 - 696

Now, solve for x: -x = -456

Finally, multiply both sides by -1 to get the value of x: x = 456

2. x + 150 = 800 - 440 Combine the constants on the right side of the equation: x + 150 = 360

Now, isolate x by moving the constant (150) to the other side: x = 360 - 150

Simplify: x = 210

3. 560 + b = 980 - 140 Combine the constants on the right side of the equation: 560 + b = 840

Now, isolate b by moving the constant (560) to the other side: b = 840 - 560

Simplify: b = 280

So, the solutions to the equations are: x = 456 x = 210 b = 280
