What is the result of adding these two equations? {:[-2x+7y=-5],[-2x-4y=6]:}

Write Equations: First, we will write down the two equations that we need to add together: Equation 1: -2x + 7y = -5 Equation 2: -2x - 4y = 6 We will add the left sides of the equations together and the right sides of the equations together.Add Equations: Adding the left sides of the equations gives us: (-2x + 7y) + (-2x - 4y) = -4x + 3y Adding the right sides of the equations gives us: -5 + 6 = 1 So, after adding the two equations, we get: -4x + 3y = 1Combine Result: Now, we have the combined equation: -4x + 3y = 1 This is the result of adding the two given equations.

Q. What is the result of adding these two equations?

\newline

\begin{array}{l} -2 x+7 y=-5 \\ -2 x-4 y=6 \end{array}

Write Equations: First, we will write down the two equations that we need to add together: $\newline$ Equation $1$ : $-2x + 7y = -5$ $\newline$ Equation $2$ : $-2x - 4y = 6$ $\newline$ We will add the left sides of the equations together and the right sides of the equations together.
Add Equations: Adding the left sides of the equations gives us: $\newline$ $(-2x + 7y) + (-2x - 4y) = -4x + 3y$ $\newline$ Adding the right sides of the equations gives us: $\newline$ $-5 + 6 = 1$ $\newline$ So, after adding the two equations, we get: $\newline$ $-4x + 3y = 1$
Combine Result: Now, we have the combined equation: $\newline$ $-4x + 3y = 1$ $\newline$ This is the result of adding the two given equations.
