Step 1: In the equation 6x - 5y = 15 everytime you see the "x" plug in y+3. This will solve for y
6(y + 3) - 5y = 15
Step 2: Distribute the 6 to all the numbers in the parentheses
6y + 18 - 5y = 15
Step 3: Combine like terms (6y and -5y)
(6y - 5y) + 18 = 15
y + 18 = 15
Step 4: Isolate y by subtracting 18 to both sides
y + (18-18) = 15 -18
y = -3
Step 5: Plug y (-3) into the equation x= y + 3 to solve for x
x = -3 + 3
x = 0
For this system of equations y = -3 and x = 0
Hope this helped!
