I think a or d is the answer sorry for not giving you the answer
Answer:
A. Add 4 to both sides and subtract 6x from both sides
Step-by-step explanation:
The correct expression is
x^2-3x+16=6x-4
Add 4 to both sides and subtract 6x from both sides
Add 4 to both sides
x^2-3x+16+4=6x-4+4
x^2-3x+20=6x
Subtract 6x from both sides
x^2-3x-6x+20=6x-6x
x^2-9x+20=0
The answer for the problems are below in the picture let me know if that makes sense.
Step 1) Solve the second equation for

Step 2) Substitute

Step 3) Substitute
−
2
for
y
in the solution to the second equation at the end of Step 1 and calculate x:
x=−5−(3×−2)
x=−5−(−6)
x=−5+6
x=1
The solution is x=1 and y=−2
