Question

x+y=5 and 2x-3y=4 solve the pair of linear eqautions by elimination method and the substitution method


dont spam spam will reported rapid firely dont think one answer all answers of spammers ​

Answer 1

Answer:

so X= 19/5, Y= 6/5

Step-by-step explanation:

x+y=5 ---------->1

2x-3y=4 -------->2

equation 1× 2 - equation 2

=> 2x+2y=10

2x-3y=4

- + -

_________

5y= 6

y= 6/5

substitute Y=6/5 in equation 1

X+ 6/5= 5

X= 5-6/5=(25-6)/5= 19/5

so X= 19/5, Y= 6/5
