Math Problem Statement

Simplify this expression: 5(2x - 3) - 4(3x + 2)

Solution

The expression given in the image is:

5(2x3)4(3x+2)5(2x - 3) - 4(3x + 2)

Let's simplify it step by step.

Step 1: Distribute the numbers outside the parentheses.

  • Distribute the 5 across the terms inside the first parentheses: 5×2x5×3=10x155 \times 2x - 5 \times 3 = 10x - 15
  • Distribute the -4 across the terms inside the second parentheses: 4×3x4×2=12x8-4 \times 3x - 4 \times 2 = -12x - 8

Step 2: Combine like terms.

Now, combine the like terms: 10x1512x810x - 15 - 12x - 8

  • Combine the xx terms: 10x12x=2x10x - 12x = -2x
  • Combine the constant terms: 158=23-15 - 8 = -23

Final Answer:

2x23-2x - 23
