Question

X + 2y = 1 and 2x + 5y = 3.

Can someone help me , with process to please ?

I will appreciate thank you so much!

Answer 1

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

2(1 - 2y) + 5y = 3

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

Answer 2

x = -1

y = 1

Explanation:

x + 2y = 1 (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1
