If, a = 2 and b = 3
Jada
[tex]10a + 1b = 7a + 5b - 3a + 4b \\ 10(2) + 1(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 20 + 3 = 14 + 15 - 6 + 12 \\ 23 = 35 \\ [/tex]
It's not equivalent.

[tex]4a + 9b = 7a + 5b - 3a + 4b \\ 4(2) + 9(3) = 7(2) + 5(3) - 3(2) + 4(3) \\ 8 + 27 = 14 + 15 - 6 + 12 \\ 35 = 35 \\ [/tex]
It's equivalent.
The correct equation is 4a + 9b.
