Final answer:
To solve the system of equations by substitution, solve one equation for one variable and substitute the expression into the other equation. In this case, solve the first equation for y, then substitute that value of y into the second equation. Solve for x and substitute the value back into the first equation to find y. The solution to the system of equations is x = -2 and y = 14.
Explanation:
To solve the system of equations by substitution, we need to solve one equation for one variable and substitute that expression into the other equation.
In this case, we can solve the first equation for y:
y = −7x
Now we substitute this value of y into the second equation:
−7x = 4x + 22
Next, we solve this equation for x:
−7x - 4x = 22
-11x = 22
x = -2
Finally, we substitute this value of x back into the first equation to find y:
y = -7(-2)
y = 14
Therefore, the solution to the system of equations is x = -2 and y = 14.

Answer:
89.98
Step-by-step explanation:
49.99 x 20% = 9.998
So, 20% of 49.99 is 10.
49.99 - 10 = 39.99 To get the Total of the discounted item.
49.99 + 39.99 = 89.98 Add final totals to get answer
