Answer:
x = 20
y = 28
Step-by-step explanation:
hari's age: x
harry's age: y
7x = 5y
4(x+4) = 3(y+4)
4x+16 = 3y+12
4x+4 = 3y
5/3(4x+4) = 5y = 7x
20/3x +20/3 = 7x
20/3 = 1/3x
x = 20
y = 28
Simplifying
2x + 9 + -10 = -5
Reorder the terms:
9 + -10 + 2x = -5
Combine like terms: 9 + -10 = -1
-1 + 2x = -5
Solving
-1 + 2x = -5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 2x = -5 + 1
Combine like terms: -1 + 1 = 0
0 + 2x = -5 + 1
2x = -5 + 1
Combine like terms: -5 + 1 = -4
2x = -4
Divide each side by '2'.
x = -2
Simplifying
x = -2
