Question

Solve by elimination method 3x+5y=1 , 2x+3y=1​

Answer 1

Answer:

• Given - 3x + 5y = 1

- 2x + 3y = 1

• To find - Solution by elimination method

• Solution -

3x + 5y = 1 -----1

2x + 3y = 1 ------2

Multipling eq. 1 with 2 and eq. 2 with 3

2 ( 3x + 5y) = 2 × 1

3( 2x + 3y) = 3 × 1

6x + 10y = 2 ---3

6x + 9y = 3 ---4

Subtract 3 from 4

y = 1

putting value of y = 1 in eq. 1

3x + 5(1) = 1

3x + 5 = 1

3x = 1 - 5

3x = (-4)

x = (-4)/3

y = 1
