6x+7y=4x+4y complete the missing value in the solution to the equation )

we have

6x+7y=4x+4y

we know that

the solution is > (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

therefore

the answer is

the missing value is x=6

The missing value in the solution to the equation is 6

Given the expression 6x+7y=4x+4y

For us to get the x-coordinate of the expression, we will substitute the value of y given into the equation and find the value of y as shown:

6x+7y=4x+4y

6x + 7(-4) = 4x + 4(-4)

6x -28 = 4x - 16

6x - 4x = -16 + 28

2x = 12

x = 6

Hence the missing value in the solution to the equation is 6

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
