Answer:
Help with what there is nothing to solve
Step-by-step explanation:
There are 4 isosceles triangles in a rectangle:)
Answer:
x = -4, y = 3/2
Step-by-step explanation:
simplify the 1st equation by dividing each term by 4 to get:
x + 2y = -1
-5x + 2y = 23
Subtract to get: 6x = -24
x = -4
find 'y': 2y - 5(-4) = 23
2y + 20 = 23
2y = 3
y = 3/2
Answer is -8
(-1)+(-7) turns into (1)+(7)=8 and then back to original which will be -8
