Bài toán 5:

a.

$x+(-13)=-144-(-78)$

$x-13=-144+78$

$x=-144+78+13=-144+91=-(144-91)=-53$

b.

$x+76=58-(-16)=58+16=74$

$x=74-76=-(76-74)=-2$
c.

$453+x=-44-(-199)=-44+199$

$x=-44+199-453=199-(453+44)=199-497$

$x=-(497-199)=-298$

d.

$-x+8=12$

$-x=12-8=4$

$x=-4$

e.

$x+8+8=7$

$x+16=7$

$x=7-16=-(16-7)=-9$

f.

$8x=-104+2^8=-104+256=256-104=152$

$x=152:8=19$

Bài 6:

a. Tập hợp các số nguyên x thỏa mãn là:

$\left\{-4; -3; ....;3\right\}$

Tổng:

$(-4)+(-3)+...+2+3=(-4)+[(-3)+3]+[(-2)+2]+[(-1)+1]+0$

$=-4+0+0+0+0=-4$

e.

Tập hợp các số nguyên x thỏa mãn là:

$\left\{-16; -15; -14;....;-1\right\}$

Tổng:

$(-16)+(-15)+(-14)+...+(-1)$

$=-(16+15+14+...+1)$

$=-\frac{16.17}{2}=-136$

23 nha

233 nha bạn

Ta có :403:x dư 12 ;217:x dư 13 và x>13

nên 403 chia hết cho x trừ 12 ;217 chia hết cho x trừ 13 

nên 391 chia hết cho x ;204 chia hết cho x [391=403 -12 ;204=217-13]

nên x thuộc ước chung của 391 và 204 

391=17 nhân 23

204=2 mũ 2 nhân 3 nhân 17

UCLN[204;391]=17

U[391;204]={1;17}

Vì x>13 nên x=17

X = 17
