What does 2x plus 9 equals 10 equal?

Answer 1

2X + 9 = 10

subtract 9 from each side

2X + 9 - 9 = 10 - 9

2X = 1

divide both sides integers by 2

(2/2)X = 1/2

X = 1/2

-----------------check in original equation

2(1/2) + 9 = 10

2/2 + 9 = 10

1 + 9 = 10

10 = 10

--------------checks [ 2(1/2) also cancels to just 1 ]
