The linear equation $3x - y = x - 1$ has:

Write four solutions for the following equation: $4y - 11 = 0$.

If the point $(a, a-2)$ lies on the graph of the equation $3x + 5y = 30$,find the value of $a$.

$x=5, y=2$ is a solution of which linear equation?

For the equation $5x + 3y = 90$,if $x = 12$,then $y = \dots$

The work done by a body on application of a constant force is the product of the constant force and the distance travelled by the body in the direction of force. Express this in the form of a linear equation in two variables and draw its graph by taking the constant force as $3$ units. What is the work done when the distance travelled is $2$ units? Verify it by plotting the graph.
