Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9
So i think its a) b) and c) because this equation is showing that if they take more time to fix the computer it will be included in x which x and y are ur solutions and also the time and the cost
3over 7 10 -2 over 2 5=1and 15
