6x+7y=4x+4y
Complete the missing value in the solution to the equation
( ,-4)

(6,-4)

Step-by-step explanation:

Points on a plane are written as coordinates (x,y)

From ( ,-4), -4 corresponds to y and x is not known.

6x + 7y = 4x + 4y

Given the value of y = -4, we solve for the value of x by substituting the value of y = -4 into the equation

Step one

We collect like terms by subtracting 7y and 4x from both sides

6x + 7y - 7y - 4x = 4x + 4y - 7y - 4x

6x - 4x = 4y - 7y

2x = -3y

But y = -4. Therefore,

2x = -3(-4)

2x = 12

Step two

Divide both sides by the coefficient of the unknown variable = 2

2x/2 = 12/2

x = 6

Therefore, the missing value in the solution to the equation is 6.

( 6, -4)

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
