Question

Solve for x

7(x+9)=4(x−8)
Give your answer as an improper fraction in its simplest form.

Answer 1

Explanation:

7(x + 9) = 4(x -8 )

7*x + 7*9 = 4*x - 4*8

7x + 63 = 4x - 32

Subtract 63 from both sides

7x = 4x - 32 - 63

7x = 4x - 95

Subtract 4x from both sides

7x - 4x = -95

3x = -95

Divide both sides by 3

x = -95/3

Answer 2

x = -95/3

Explanation:

7(x+9)=4(x−8)

Distribute

7x+63 = 4x - 32

Subtract 4x

7x+63-4x = 4x-32-4x

3x+63 = -32

Subtract 63

3x+63-63 = -32-63

3x= -95

Divide by 3

3x/3 = -95/3

x = -95/3
