Question

What is the x-coordinate of the point in the stan- dard (x, y) coordinate plane at which the two lines y = - 2x + 7 and y = 3x - 3 intersect? A. 10B. 5 C. 3D. 2 E. 1

Answer 1

we can equalize the equations and solve x

`-2x+7=3x-3`
`\begin{gathered} 7+3=3x+2x \\ 10=5x \\ x=2 \end{gathered}`

the option is D
