I assume that the question means 4x-7=2x+5. In that case, the answer x would equal 6.

y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
4x - 5 + 2x = 376x - 5 = 376x = 37 + 56x = 42x = 42 / 6x = 7

Well take your pick either 4x-7 = -28 .... -28 -2 = -30 .... -30x5 = -150 or 4x-7 = -28 .... (-2x5=-10) .... -28-10 = -38
