What is the solution to the following pair of simultaneous equations?𝑦=2𝑥+12𝑦−𝑥=−1y=2x+12y−x=−1
Question
Solution 1
The pair of simultaneous equations given are:
- y = 2x + 1
- y - x = -1
Let's solve them step by step:
Step 1: From equation 2), we can express x in terms of y: x = y + 1
Step 2: Substitute x from step 1) into equation 1): y = 2(y + 1) + 1
Step 3: Simplify the equation: y = 2y + 2 + 1
