6X - 28 = 4X - 16

6X - 4X = - 16 + 28

2X = 12

X =6

To find:

Complete the missing value in the solution to the equation.

(__,-4)

Explanation:

Given that the value of y = -4 and find the value of x

6x+7y=4x+4y

6x - 4x = 4y -7y

2x = -3y

Putting the value of y in above equation.

2x = -3y

2x = -3(-4)

2x = 12

 x = $\frac{12}{2}$

 x = 6

Missing value in the solution to the equation.
