6. Lets assume a number x
so other number is x + 42
Equation:
x + 42 + x = 108
2x + 42 = 108
2x = 108-42
2x = 66
x = 33
x + 42 = 33+42 = 75
7. Let the number be x
13x - 10x = 99
3x = 99
x = 99/3
x = 33
13x = 33 × 13 = 429
10x = 33 × 10 = 330
so other number is x + 42
Equation:
x + 42 + x = 108
2x + 42 = 108
2x = 108-42
2x = 66
x = 33
x + 42 = 33+42 = 75
7. Let the number be x
13x - 10x = 99
3x = 99
x = 99/3
x = 33
13x = 33 × 13 = 429
10x = 33 × 10 = 330
