Question

1 .2y+16+y+23=180 ,berapakah nilai y

2. 3x+6+2x+4=180 ,berapakah nilai x

3. 8x-2+6x+12=180 ,berapakah nilai x

Answer 1

1. 2y +16 +y +23 = 180
   3y +39 = 180
   3y = 180 -39
   3y = 141
   y = 141/3
   y = 47

2. 3x +6 +2x +4 = 180
     5x +10 = 180
     5x = 180 -10
     5x = 170
     x = 170/5
     x = 34

3. 8x -2 +6x +12 = 180
   14x +10 = 180
   14x = 180 -10
   14x = 170
   x = 170/14
   x = 12 2/14
   x = 12 1/7

Itu jawabannya.

Answer 2

1. 2y + 16 + y + 23 = 180
     3y + 39 = 180
     3y = 180 - 39
     3y = 141
     y = 141 / 3
     y = 47

2. 3x + 6 + 2x + 4 = 180
     5x + 10 = 180
     5x = 180 - 10
     5x = 170
     x = 170 / 5
     x = 34

3. 8x - 2 + 6x + 12 = 180
   14x + 10 = 180
   14x = 180 - 10
   14x = 170
   x = 170 / 14
   x = 12, 14
