7x - 4y = -28

3x +4y = -12

Using the elimination method because y is already eliminated

10x = -40

So x = -4

Then plug the -4 into the first equation....

7(-4) - 4y = -28

-28 - 4y = -28

-4y = 0

y = 0

I got:  -4,0

Which statement is true about this equation? 3(-y 7) = 3(y 5) 6.
Ahat [919]

The statement that is true about the equation 3(-y + 7) = 3(y + 5) + 6 is;

Statement A; The equation has one solution, y = 0

The given equation is;

3(-y + 7) = 3(y + 5) + 6

Expanding the brackets gives us;

-3y + 21 = 3y + 15 + 6

-3y + 21 = 3y + 21

Using subtraction property of equality, subtract 21 from both sides to give;

-3y = 3y

Using addition property of equality, add 3y to both sides to give;

-3y + 3y = 3y + 3y

6y = 0

Using division property of equality, divide both sides by 6 to get;

y = 0

A. The equation has one solution, y = 0.

B. The equation has one solution, y = -1.

C. The equation has no solution.

D. The equation has infinitely many solutions.

the new is 15 old is 799
799-15=784x100
the high number is 799
