to eliminate the y-terms and solve for x in the fewest steps, by which constants should the equations be multiplied? first equat
Mazyrski [523]

Answer: The first equation should be multiplied by 9 and the second equation by −4, to eliminate the y-terms and solve for x in the fewest steps.


Step-by-step explanation:

Given : Equation (1) 5x − 4y = 28

Equation (2) 3x - 9y = 30

to eliminate the y-terms and solve for x in the fewest steps, we should multiply  equation (1) by 9 and equation (2) by -4 such that

9(5x − 4y) =9 (28)⇒45x-36y=252

-4(3x - 9y) = -4(30)⇒ -12x+36y= -120

Now adding both equations, y-term eliminated and we get, 45x-12x=132

⇒33x=132⇒x=4.
