1) <span>-16a+3+7a-6 = -9a - 3
2) </span><span>14x+8y+12y-20x = 20y - 6x
3) </span><span>-3(8p-6)+4p = 18-20p
4) </span>(9x+2y-8) - (12x+11 = -3x + 2y - 19
6)
80+160+100+8x+8+5x+10=540
13x + 358 = 540
13x = 540 -358
13x = 182
x = 182/13
x = 14
answer x =14
7)
7x+13=8x-8
8x-7x=13+8
x = 21
answer x = 21
Answer:
