Answer:
Square
x = 2
y = 1
Step-by-step explanation:
Measures of all ll sides of a square are equal.
Therefore,
5x - 4 = 3x
5x - 3x = 4
2x = 4
x = 4/2
5y + 1 = 2y + 4
5y - 2y = 4 - 1
3y = 3
y = 3/3
7 y and 8x first add the 2 number with y together and then you take away the 1 with the x and then you add both of them together
