Question

(8х+4)-(2х+1)•2+(4+4х)=?​

Answer 1

$(8x + 4) - (2x + 1) \times 2 + (4 + 4x) = (8x + 4) - (4x + 2) + (4 + 4x) = 8x + 4 - 4x - 2 + 4 + 4x = 8x - 4x + 4x + 4 - 2 + 4 = \boldsymbol{8x + 6}$

Answer 2

(8х + 4) - (2х + 1) * 2 + (4 + 4х) = (8x + 4) - 2 * (2x + 1) + (4 + 4x) = 8x + 4 - 4x - 2 + 4 + 4x = 8x + 6
