Answer:
quadrant 1 that the graph is mainly in
X = small van capacity, y = larger van capacity
y = x + 6
2x + y = 57
now we sub in x + 6 for y
2x + x + 6 = 57
3x + 6 = 57
3x = 57 - 6
3x = 51
x = 51/3
x = 17
y = x + 6
y = 17 + 6
y = 23
small van (x) has 17 seats and large van (y) has 23 seats
In order to move a number that is multiplied or divided by the variable<span>, you must do the inverse to both sides. That means, if the number is multiplied, you must divide it by both sides. If it's divided, you must </span>multiply<span> it by both side. steps so that you can apply them to more complex </span>problems<span>.</span>
