Verified answer

7(8-2x)+3x

Multiply 7 to both terms in brackets

56-14x+3x

So i think the answer would be 56-11x

Distribute first: 7*8 is 76 and 7*2x is 14x so you get 76-14x+3x. Then combine like-terms: -14x+3x is -11x so your answer would be 76-11x

First: a million. 6 * 9T = sixty 4 T 6 * (-2) = -12 4* 3T = 12 T 4 * (-7) = -28 = 64T +12 + 12T + 28 = seventy six T + 40 the second one: 8 * 13P = 104 P 8 * 1R = 8R 8 * (-12P) = -96P 12 - 104P - 8R + 96P = 12 - 8P - 8R third: 23 - 4 + 12Y - 34Z + 108 = 19 + 12Y - 34Z + 108 = 127 + 12Y - 34Z I did it in information.. wish you understood :)
