Ok to solve your first expression follow these steps 1. Simplifying 3(x + -4) + 5(x + 6)  2. Reorder the terms 3(-4 + x) + 5(x + 6)   (-4 3 + x 3) + 5(x + 6)   (-12 + 3x) + 5(x + 6)  3. Reorder the terms -12 + 3x + 5(6 + x) -12 + 3x + (6 5 + x 5)  -12 + 3x + (30 + 5x)  4. Reorder the terms -12 + 30 + 3x + 5x  5. Combine like terms -12 + 30 = 18 + 3x + 5x  6. Combine like terms 3x + 5x = 8x + 18 and  that's your answer do you understand?
