Question

9x+5y=34
8x-2y=-2
What are the values of x and y? Please explain the steps.​

Answer 1

x = 1 and y =5

Explanation:

`8x -2y= -2\\Divide by -2\\-4x+y = 1\\add 4x\\y= 1+4x\\`

Substitute this value of y in the next equation.

`9x+5(1+4x) = 34\\9x+5+20x=34\\29x+5=34\\29x=29\\x=1`

Solve for y using x.

`y=4x+1\\y=4(1)+1\\y=5`
