Here's how to solve the simultaneous equations:
Step 1: Write down the given equations.
2x+y=5(i)
x+y=6(ii)
Step 2: Subtract equation (ii) from equation (i) to eliminate y.
(2x+y)−(x+y)=5−6
2x−x+y−y=−1
x=−1
Step 3: Substitute the value of x into equation (ii) to find y.
x+y=6
−1+y=6
y=6+1
y=7
The solution is x=−1 and y=7.
x=−1,y=7
