Question

X-340:10=12•5 484:4+x=210

Answer 1

Ответ:

94.....................89

Пошаговое объяснение:

Х-340/10=12*5

Х-34=60

Х=60+34

Х=94

484/4+х=210

121+х=210

210-121=х

х=89

Answer 2

Let's solve the given equations step by step:

1. X - 340 = 12 * 5

To solve this equation, we'll perform the operations in the following order:

1. Multiply: 12 * 5 = 60
2. Subtract: X - 340 = 60

To isolate X, we'll add 340 to both sides of the equation: X - 340 + 340 = 60 + 340 X = 400

Therefore, X = 400.

2. 484 : 4 + X = 210

To solve this equation, we'll perform the operations in the following order:

1. Divide: 484 / 4 = 121
2. Add: 121 + X = 210

To isolate X, we'll subtract 121 from both sides of the equation: 121 + X - 121 = 210 - 121 X = 89

Therefore, X = 89.

Final solutions:

1. X = 400
2. X = 89
