To eliminate the x-terms and solve for y
you need to multiply (7) to the first equation
6x − 5y = 17 ( multiply 7)
42x - 35y = 119
------------------------------------------
Now you need to multiply(6) to the second equation
7x + 3y = 11 ( multiply 6)
42x + 18y = 66
Now you have 2 new equations
42x - 35y = 119
42x + 18y = 66
You can subtract those two equation to eliminate x and solve for y

Answer:
Multiply the first equation by -7 and second equation by 6
Step-by-step explanation:
First equation: [tex]6x - 5y = 17[/tex]
Second equation: [tex]7x + 3y = 11[/tex]
To eliminate x terms, the coefficient of x should be same with different sign.
WE have different coefficient of x.
To get same coefficient for x , we multiply both equation by opposite coefficients.
Multiply the first equation by -7 and second equation by 6
To eliminate the x-terms and solve for y , Multiply the first equation by -7 and second equation by 6
