3(x + 1) + 4(2x + 3)
= 3*x + 3*1 + 4*2x + 4*3
= 3x + 3 + 8x + 12
= 3x + 8x + 3 + 12
= 11x + 15
= 3*x + 3*1 + 4*2x + 4*3
= 3x + 3 + 8x + 12
= 3x + 8x + 3 + 12
= 11x + 15

3(x + 1) + 4(2x + 3) =
3x + 3 + 8x + 12 =
11x + 15
3x + 3 + 8x + 12 =
11x + 15

what do u mean expand?
to simplify you would first distribute the 3 to the parentheses and the 4 to the parentheses
3x+3+8x+12
11x +3+12
11x +15
