Question

3 (x+5)+4х упростите выражение

Answer 1

3(x+5)+4x=3x+15+4x=15+7x

Answer 2

To simplify the expression 3(x+5) + 4x, you can distribute the 3 over the terms inside the parentheses, and then combine like terms. Here's the step-by-step simplification:

Step 1: Distribute the 3 over the terms inside the parentheses: 3(x + 5) = 3x + 3 * 5 = 3x + 15

Step 2: Now the expression becomes: 3x + 15 + 4x

Step 3: Combine like terms (terms with the same variable, x, raised to the same power): 3x + 4x = 7x

So, the simplified expression is: 7x + 15
