Solve the system of equations - x - y = 6 and 5x -7y=66 by combining the equations
1 answer:
Answer: Let's solve for x.
−x−y=6
Step 1: Add y to both sides.
−x−y+y=6+y
−x=y+6
Step 2: Divide both sides by -1.
−x
−1
=
y+6
−1
x=−y−6
Answer:
x=−y−6
Let's solve for x.
5x−7y=66
Step 1: Add 7y to both sides.
5x−7y+7y=66+7y
5x=7y+66
Step 2: Divide both sides by 5.
5x

=
7y+66

Square has 4 sides equal
garden has 4 sides of 50 each (4 times 50=200)
each smal garden is 10.5 times 4 sinc ethey also have 4 sides
10.5*4=42
times 3 since 3 of them
42*3=126
add to find total
garden+3rosebuds=200+126=326 ft^2
