Hi there! :)

\large\boxed{x = 3}

According to the exterior angle theorem, the angle ∠ADC is equal to the sum of ∠C and ∠B. Therefore:

120 = (15 + 5) + (22x + 4)

Combine like terms:

120 = 37x + 9

Subtract 9 from both sides:

111 = 37x

Divide both sides by 37:

x = 3.

NikAS [45]
The answer is The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and <span>5x + 5y = 50 is (8, 2)

Harry's money is $ 32

He said that he spent ALL of his money buying 3 Notebooksx and 4 cards y, so the equation that represent this is </span> 
3x + 4y = 32 .

He said that HE IS SHORT $18 if he wants to buy 5 notebook x and 5 cards y,
So the equation that represent this is
5x + 5y = 32 + (18)
5x + 5y = 50

And (8,2) is the only one that fit in both equation/
