The given system of equations are

y=-3x/2 + 6

y=5x - 7

We would substitute values for x into the equations and find the corresponding y values. These values would be plotted on a graph. Where the lines of both equations meet would represent the solution of the system of equations.

For the first equation,

y = - 3x/2 + 6

if x = 0, y = 3 * 0/2 + 6 = 6

If x = 1, y = - 3 * 1/2 + 6 = 4.5

if x = 2, y = - 3 * 2/2 + 6 = 3

We would plot these values on the graph

For the second equation,

y = 5x - 7

if x = 0, y = 5 * 0 - 7 = - 7

If x = 1, y = 5 * 1 - 7 = - 2

if x = 2, y = 5 * 2 - 7 = 3

We would plot these values on the graph

The diagram of the graph is shown below

Looking at the graph, at the point where both lines meet,

x = 2, y = 3

Thus, the solution is (2,3)
