Question

56:4+х=257, 2)а +84:4=570

Answer 1

Ответ:

x = 243

a = 549

Пошаговое объяснение:

1). 56:4+х=257

x = 257 - 56 : 4

x = 257 - 14

x = 243

2). а +84:4=570

a = 570 - 84 : 4

a = 570 - 21

a = 549

Answer 2

To solve the equations, we'll find the values of the variables, x and а.

1. 56 + 4x = 257

To solve for x, we need to isolate it on one side of the equation. Follow these steps:

Step 1: Subtract 56 from both sides to move the constant term to the right side. 56 + 4x - 56 = 257 - 56 4x = 201

Step 2: Divide both sides by 4 to solve for x. x = 201 / 4 x = 50.25

So, the value of x is 50.25.

2. a + 84 / 4 = 570

To solve for a, follow these steps:

Step 1: Subtract 84/4 from both sides to move the constant term to the right side. a + 84/4 - 84/4 = 570 - 84/4 a = 570 - 21 a = 549

So, the value of a is 549.
