Answer:
Step-by-step explanation:
g = s + 75
g + s = 525
That's just the answer for (a). You'll have to graph it yourself.
Guide to the methodology:
You need to plot 2 points for each equation and draw a line between the points. Where the two lines intersect gives you the values that solve the equations.
To get your co-ords,
Let g = 0
s = -75
Create a graph with g as one axis and s as the other. Plot a point of (0,-75)
Let s = 0
g = 75
Plot another point (0,75)
Draw a line between the two points. This is your line for g = s +75
You then need to plot a line for the second equation.
Let g = 0. S = 525. First co-ordinate is (0,525)
Let s = 0. G = 525. Second co-ordinate is (525,0)
