The gymnasts blank body moved gracefully masterfully across the balance beam never missing a beat or her step which word best completes the sentence below? a. agile b. lengthy c. spry d. subtle hurryyy ! someone hlppp

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

answer: this is easy, i found "it"

i will repeat the question again, "find it."
