Hi!
For this equation, you can solve it by using the quadratic formula:
x=-b<span>±sqrt/b^2-4ab
-----------------------
2a</span>
Look up on desmos it will give the correct answer
-7x + 6 =27
subtract 6 from both sides
-7x =21
divide both sides by -7
x= -3
Answer:60
Step-by-step explanation: x=10
-7+9=2*10=20
-10*10=100
180-100-20=60
