4x-9y=9
-x+3y=6
Consider the system of linear equations below.

Rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

ax+by=c

Respuesta :

Answer:

Second equation:

Answer:

-3x + 9y = 18

Step-by-step explanation:

4x - 9y = 9

-x + 3y = 6

Multiply both sides of the second equation by 3 to eliminate the variable y after adding the equations.

-3x + 9y = 18
