What does x equal to?

Step-by-step explanation:

7x + 1 + 10x - 9 = 19x - 18

17x - 8 = 19x - 18

-2x - 8 = -18

-2x = -10

x = 5 the solution

7(5)+1= 36

10(5) - 9 = 50 - 9 = 41

19(5) - 18 = 95 - 18 = 77

i think it is 70

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
