Question

Which equation is part of solving the system by substitution?

StartLayout Enlarged left-brace 1st Row x + y = 11 2nd row 4 x squared minus 3 y squared = 8 EndLayout
4(y + 11)2 – 3y2 = 8
4(11 – y)2 – 3y2 = 8
4(y – 11)2 – 3y2 = 8
4(–11y)2 – 3y2 = 8

Answer 1

The equation that is part of solving the system by substitution is 4(11 – y)2 – 3y2 = 8. To solve the system of equations using substitution, solve the first equation for x and substitute it into the second equation. Simplify and solve the resulting equation to find the values of x and y.

Step-by-step explanation:

The equation that is part of solving the system by substitution is 4(11 – y)2 – 3y2 = 8.

To solve the system of equations using substitution, we can start by solving one equation for one variable and then substituting that expression into the other equation. In this case, we can solve the first equation for x, which gives us x = 11 - y. Substituting this expression for x into the second equation, we get 4(11 - y)2 - 3y2 = 8.

By simplifying and solving this equation, we can find the value of y, which can then be substituted back into the first equation to find the value of x.

Answer 2

4(11-y)²-3y²=8

Step-by-step explanation:

x+y=11

x=11-y
