Question

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

Answer 1

Answer:

2x(1)-3x(1)=7

2-3=7

2x(1)-3y not equal to x+y=1

Answer 2

Answer:

y= (-3/5)

x=(8/5)

Step-by-step explanation:

2x-3y=7

x+y=1

Taking First Eqn:

x=7+3y/2----(1)

Now taking eqn (1) and substituting in the original equation

7+3y/2+y=1

(3y+2y)/2= (-6)

5y/2= (-6)

5y=(-3)

y= (-3/5)

x=(8/5)
