A garden is in the shape of an isosceles triangle, a triangle that has two sides of equal measure. The length of the third side is 2 feet greater than the length of the equal sides. If the perimeter of the triangle of the garden is 86 feet, find the length of each side of the triangle.

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?
