Given the system of equations. which of the options represents the resulting equation after an equivalent expression for y is substituted into the second equation. (see picture.) a) 2x - (4x + 3) = 12 b) -4x + 4x - 3 = 3 c) 2 (4x + 3) - y d) -4(4y + ) + y = 3

20y5 times 2 is 1010 times -2 is -20, plus y

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
