Question

System of equations. 4x-2y=22 7x+5y=4

Answer 1

Given system of equation is,

`\begin{gathered} 4x-2y=22\ldots..(1) \\ 7x+5y=4\ldots\text{.}\ldots(2) \end{gathered}`

To find the values for x and y,

Multiply euqation (1) by 5 + equation (2) by 2, it becomes

`\begin{gathered} 20x-10y+14x+10y=110+8 \\ 34x=118 \\ x=(59)/(17) \end{gathered}`

Put the value of x in equation (1)
