⦁the group is planning to build a fence around the garden. how many yards of fencing materials do they need for the fence? show your work. (3 points—2 points for finding the value of side b and 1 point for finding the perimeter of the garden)

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
