Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by substitution.
4x + 5y = 9 ; 4x − 2y = 2
- Solve 4x + 5y = 9 for x:
4x + 5y = 9
4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)
4x = − 5y + 9
Then Substitute for x in 4x - 2y = 2
4x − 2y = 2
4() − 2y = 2
− 7y + 9 = 2 (Simplify both sides of the equation)
− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)
− 7y = − 7
(Divide both sides by -7)
y = 1
Substitute 1 for y in x =
x = 1
So, x = 1 and y = 1

Answer:
Step-by-step explanation:
7.07 to the power of 2 = 49.9849
4.24 to the power of 2 = 17.9776
49.9849/17.9776 = 2.7803989
The square root of 2.78039894 = 1.66745283
1.66745283 times 2 + 4.24 times 2 = 11.8149057 rounded is 11.81
