Question

2. (15i +14b + 13 k) + (-30i - 45j +51k)=

3. tentukan hsil penjumlahan ( 3 - 17x + 35z) dan ( 4x + 23y -9)

4. (42n + 35m + 7) - ( 50m- 20n +9)=

5. tentukan hasil pengurangan (5x+3) oleh (x-1)

Answer 1

4. (42n+35m+7)-(50m-20n+9)
=42n-20n+35m-50m+7+9
=22n-15m+16

5. 5x+3-(x-1)
5x-x+3-1 =
= 4x+2

Answer 2

1. (15i +14b +13k) +(-30i -45j +51k)
     15i +14b +13k -30i -45j +51k
     15i -30i +14b +13k +51k -45j
     -15i +14b +64 k -45j
2. (3 -17x +35z) +(4x +23y -9)
     3 -17x +35z +4x +23y -9
   -17x +4x +35z +23y +3 -9
   -13x +35z +23y -6
3. (42n +35m +7) -(50m -20n +9)
     42n +35m +7 -50m +20n -9
     42n +20n +35m -50m +7 -9
     62n -15m -2
4. (5x +3) -(x -1)
     5x +3 -x +1
     5x -x +3 +1
     4x +4
