3x - 5y = 10 6x + 3y = -6 marybeth is going to solve this problem by multiplying the top equation by -2. if she does this and combines the equations, what does she get? a) -13y = -26 b) -7y = 14 c) -2y = 4 d) 13y = -26

On multiplying with -2 in the equation given in the question we get as 13y = -26

Option(d)

Step by Step Explanation:

Solution;

The given two set of equations such as

(Equation 1)

(Equation 2)

Also given, Marybeth multiplies the first equation by -2

After multiplying with -2 in first equation we get

Adding the newly obtained equation 1 and Equation 2,

Adding the like terms x, y and constants we get

13y=-26

Result:

Thus on multiplying and simplifying the above two equations gives answer as 13y = -26
