For this case we must find the solution of the following equation:
Applying distributive property on the right side of the equation we have:
Subtracting 7x from both sides of the equation:
Subtracting 20 from both sides of the equation:
Different signs are subtracted and the major sign is placed.
Dividing between -2 on both sides of the equation:
Thus, the solution of the equation is
Answer:
The complete question is :
Question: What is the coefficient in the expression 10x²-7?
The coefficient in the expression is 10
