Question

How do you solve the system of equations and enter the solution as an ordered pair. 4x-7y=-23 & 8x+5y=49?

Answer 1

`y = 0.16`

`x= 6.06`

Explanation:

`4x-7y = 23` Eqn 1
`8x+5y = 49` Eqn 2
Multiply Eqn 1 by 2

`8x-14y = 46`
Subtract Eqn 2,

`-19y =- 3, y = 3/19 = 0.16`

Substituting value of y in Eqn 1
`4x-(21/19) = 23`
`x =( 24(2/19))/4 = 6.06`
