the top righ andt doesn't belong to each other because the first antenna is at the left. equal means it needs to have a connection or its have to be absolutely the same. in this case the equal picture is not the same
Answer:
10 or 4.
Step-by-step explanation:
[(x - 7)^2 + 6 - 13 ] * 4 - 1 = 7
(x^2 - 14x + 49 - 7) * 4 - 1 = 7
4x^2 - 56x + 196 - 28 - 1 - 7 = 0
4x^2 - 56x + 160 = 0
4(x^2 - 14x + 40) = 0
(x - 10)(x - 4) = 0
x = 10 , 4
X = y - 3 (equation 1)
2x + y = 12 (equation 2)
Substitute equation 1 into equation 2, replacing every x value with equation 1
2(y - 3) + y = 12
Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)
Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3
Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12
Therefore, x = 3 and y = 6
