Question

Solve the following system of linear equations by using the method of substitution
2x - 3y= 7; x+y= 1​

Answer 1

Answer:

x = 2, y = -1.

Step-by-step explanation:

2x - 3y = 7

x + y = 1

x = (1 - y).

2(1 - y) - 3y = 7

2 - 2y - 3y = 7

2 - 5y = 7

-5y = 5

y = -1.

So x + (-1) = 1.

x = 2.
