Step 1 :Step 1: Multiply the first equation by -2: \( -4x - 2y = -20 \)
Step 2 :Step 2: Add the second equation to the new first equation: \( -y = -5 \)
Step 3 :Step 3: Solve for y: \( y = 5 \)
Step 4 :Step 4: Substitute the value of y back into the first equation: \( 2x + 5 = 10 \)
Step 5 :Step 5: Solve for x: \( x = 2.5 \)
Step 6 :Step 6: The solution to the system of equations is \( (2.5, -5) \)
