6x+7y=4x+4y6x+7y=4x+4y6, x, plus, 7, y, equals, 4, x, plus, 4, y Complete the missing value in the solution to the equation. ((left parenthesis ,-4),−4)

Step-by-step explanation:

Given:

6x+7y=4x+4y.

(  ,-4)

Now, to complete the missing value in the solution to the equation.

As, the equation is:

And, the solution is:

Now, solving the equation by putting the value of :

Adding both sides by 28 we get:

Subtracting both sides by we get:

Dividing both sides by 2 we get:

Thus, the solution to the equation is (6, -4).

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

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
