Select the best possible first step to solving the system by first eliminating the x variable.3x − 9y = 6 2x − 11y = 6?

x=4/5

y=-2/5

Step-by-step explanation:

We have two equations:

We can eliminate x by making x of equation 1 be equal to x in the equation 2:

Substitute into equation 2:

Simplify:

Substitute back into one of the equations:

sorry, i don't know i just need points, i'm new here. chao

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
