Solve the following system of linear equations: x + y = 7; 2x - 3y = 4. Hence, obtain the value of 3x-2ya.2b.5c.7d.11
Question
Solution 1
Sure, let's solve the system of linear equations first:
- x + y = 7
- 2x - 3y = 4
Step 1: Solve the first equation for x:
x = 7 - y
Step 2: Substitute x in the second equation:
2(7 - y) - 3y = 4 14 - 2y - 3y = 4 14 - 5y = 4 5y = 14 - 4 5y = 10 y = 10 / 5 y = 2
Step 3: Substitute y = 2 into t Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
