Step 1: To determine
Given:
The system of equations 4x−3y=−10 & 2x+3y=4
To determine:
Which is the correct step to solve the given system of equations.
Step 2: Calculation
The correct step is to add the two equations so that the variable y gets eliminated easily.
On adding both equations, we get,
4x−3y+2x+3y=−10+4
4x+2x=6
6x=6
x=1
Substituting value of x=−1 in first equation, we get,
4(−1)−3y=−10
43y=10
3y=10+4
3y=6
y=63=2
y=2
Hence, adding both equations is the correct step to solve the given system of equations.
