Question

3x+7y=10 and 2x+y=3( substitution method) ​

Answer 1

Answer:

Hey , for substition method find the value of either x or y , since i like x ill take the x value from the second equation

Step-by-step explanation:

2x+y=3

==>2x=3-y

==>x=3/2-y/2

(we found the value of x)

NOW SUBSTITUTE X VALUE IN 1st EQUATION :

3x+7y=10

==> 3 (3/2-y/2) +7y=10

==>3(3/2-y/2)+7y=10

==>(9/2-3y/2)+7y=10

==> 9-3y +14y = 2(MULTIPLY EVERY TERM BY 2)

==>9-11Y=10

==> 9 = 10 +11Y

==> 11Y = 9 - 10

==> Y=  -1/11

NOW SUBSTITUTE Y VALUE IN x=3/2-y/2 AND YOU WILL GET X VALUE TOO

HOPE IT HELPED :)
