Answer 1

Ответ:

5x+2x+60=280

7x=220

x=220/7

Answer 2

To solve the equation, follow these steps:

Step 1: Distribute the 2 into the parentheses. Step 2: Combine like terms on the left side of the equation. Step 3: Isolate the variable (x) on one side of the equation. Step 4: Solve for x.

Let's proceed with the solution:

1. Distribute the 2 into the parentheses: 5x + 2(x + 30) = 280 5x + 2x + 60 = 280

2. Combine like terms on the left side: 7x + 60 = 280

3. Isolate the variable (x) on one side: Subtract 60 from both sides to move it to the right side of the equation: 7x = 280 - 60 7x = 220

4. Solve for x: Divide both sides by 7 to isolate x: x = 220 / 7 x ≈ 31.43

So, the solution to the equation is approximately x = 31.43.
