If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation. 6x − y = 1 4x − 3y = −11 (6 points) Group of answer choices 4(−6x + 1) − 3y = −11 4(6x + 1) − 3y = −11 4x − 3(6x − 1) = −11 4x − 3(−6x − 1) = −11

Sagot :

The new equation that will be formed is x − 3(6x − 1) = −11 (third option).

What is the substitution method?

The substitution method is one of the methods that is used to solve simultaneous equations. It entails making one of the variables subject of the formula and substituting for it in the second equation.  Other methods that can be used to solve simultaneous equations are the graph method and the elimination method.

The two simultaneous equations given are:

6x − y = 1 equation 1

4x − 3y = −11 equation 2

When y in equation 1 is made subject of the formula, the equation formed is:

y = 6x - 1 equation 3

Substitute for y in equation 2

4x - 3(6x - 1) = -11
