Question

3x+4y=10
2x-2y=2
By substitution method

Answer 1

Answer:

X=2

Y=1

Step-by-step explanation:

Solved by substitution method

Answer 2

3x + 4y = 10

2x - 2y = 2

________________ [GIVEN]

• We have to find the value of x and y.

_______________________________

=> 3x + 4y = 10 ______ (eq 1)

=> 2x - 2y = 2

=> x - y = 1

=> x = 1 + y _____ (eq 2)

• Put value of x in (eq 1)

=> 3(3 + y) + 4y = 10

=> 3 + 3y + 4y = 10

=> 7y = 7

=> y = 1

• Put value of y in (eq 2)

=> x = 1 + 1

=> x = 2

_____________________________

x = 2 and y = 1
