Soalan nombor 1 tak berapa jelas bagi saya la. 2. 8(-4)8^3 - 4(-4)(7) = -512 - 112 = -624.
3) 3y= -5 - 4
    3y= -9
    y= -9/3
    y= -3

4) 6p+12/3 = 9
    6p+12 = 9x3
    6p+12 = 27
          6p = 27 - 12
            p = 15/6
            p = 2.5
  
1.y per 3-11+2y, terima kasih sgt sbb bantu saya!

1)mula² samakan
y/3+2y-11
=y/3+6y/3-11
=7y/3-11#
2)8(-4³)-4(-4)(7)
=8(-64)-4(-28)
=-512+112
=-400#
3)4-3y=-5
-3y=-5-4
-3y=-9
y=-9÷(-3)
=3#
4)6(p+2)/3=27
6(p+2)=3×9
p+2=27/6
P=4.5-2
=2.5#
1 5 1
terima kasih ia sgt membantu! :))
