Hi, I have some maths works to do but I didn't get anything can you do it for me please and show the work

Answer 1

Given:

`\begin{gathered} y=2x-1\text{ } \\ 2x+y=3 \end{gathered}`

Find: solve the given equations by substitution method

Explanation:

`\begin{gathered} y=2x-1.................(1) \\ 2x+y=3.................(2) \end{gathered}`

put the value of y from equation (1) into equation (2) .

`\begin{gathered} 2x+2x-1=3 \\ 4x=4 \\ x=(4)/(4)=1 \\ y=2x-1 \\ =2*1-1 \\ =2-1 \\ =1 \end{gathered}`

Final answer: the required solution is x=1 and y=1.
