求下列的答案:
1.(-36)+(-9)-(-18)=-27
2.(-8)x(-2)x(+3)=48
3.(+3)除(-7)除(+七分之一)=-3
請解下列方程
1.x-10=-8, x= -8+10 = 2
2.2x+5=-11, x= (-11-5)/2 = -8
3.二分之3x=八份之九, x=((9/8)(2/3) = 3/4
4.12+3x=4-5x, 3x+5x=4-12, 8x=-8, x=-1
1.(-36)+(-9)-(-18)=-27
2.(-8)x(-2)x(+3)=48
3.(+3)除(-7)除(+七分之一)=-3
請解下列方程
1.x-10=-8, x= -8+10 = 2
2.2x+5=-11, x= (-11-5)/2 = -8
3.二分之3x=八份之九, x=((9/8)(2/3) = 3/4
4.12+3x=4-5x, 3x+5x=4-12, 8x=-8, x=-1
