Solve the system by substitution x=y 6x-3y=30

1 answer:

8 0

Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

i hope this helps! :D

Answer: Let's solve your equation step-by-step.

2h−3=3

Step 1: Add 3 to both sides.

2h−3+3=3+3

2h=6

Step 2: Divide both sides by 2.

2h/2 = 6/2

h = 3.
