Answer:
4) add the equations to eliminate x
Step-by-step explanation:
After adding the equations then you can use the value you found for y to substitute back into one of the equations in order to find x
Answer:
Step-by-step explanation:
1. Subtract 9 from both sides of the equation:
2. Notice that the coefficient of "x" is 7. Then:
3. Add 
to both sides of the equation:
4. Completing the square, you get:
5. To find the solutions, you must square-root both sides of the equation, simplify, and solve for "x". Then, you get:
Answer:
The coefficient is 3
Step-by-step explanation:
The definition of a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy).
Y=-1.5x + 8
