To solve the system of equations using substitution, we start with the two equations provided:
1. \( -4x + y = 0 \) (Equation 1)
2. \( 2x - 3y = -10 \) (Equation 2)
First, we can solve Equation 1 for \( y \):
\[
y = 4x
\]
Next, we substitute \( y = 4x \) into Equation 2:
\[
2x - 3(4x) = -10
\]
This simplifies to:
\[
2x - 12x = -10
\]
\[
-10x = -10
\]
\[
x = 1
\]
Now that we have the value of \( x \), we can find \( y \) by substituting \( x = 1 \) back into our expression for \( y \):
\[
y = 4(1) = 4
\]
Thus, the solution to the system of equations is:
\[
(x, y) = (1, 4)
\]
Therefore, the answer is:
\((1, 4)\)
1. \( -4x + y = 0 \) (Equation 1)
2. \( 2x - 3y = -10 \) (Equation 2)
First, we can solve Equation 1 for \( y \):
\[
y = 4x
\]
Next, we substitute \( y = 4x \) into Equation 2:
\[
2x - 3(4x) = -10
\]
This simplifies to:
\[
2x - 12x = -10
\]
\[
-10x = -10
\]
\[
x = 1
\]
Now that we have the value of \( x \), we can find \( y \) by substituting \( x = 1 \) back into our expression for \( y \):
\[
y = 4(1) = 4
\]
Thus, the solution to the system of equations is:
\[
(x, y) = (1, 4)
\]
Therefore, the answer is:
\((1, 4)\)
