Why are there two directions?3x + 2y = 2, -2x + y = 8 Let us just solve by testing each of the options. Option A is (-2, 4), that is x =-2 and y = 4 check: for x = -2 and y = 4 3x + 2y = 2 3-2 + 24 -6 + 8 = 2 2 = 2 So both sides are equal. -2x + y = 8 x = -2 and y = 4 -2*-2 + 4 4 + 4 8 8 = 8 Since option A (-2, 4) satisfies both equation, no need to test other options.Toán Lớp 8: "Những hằng đẳng thức đáng nhớ": 1, Tính: a, (3x^2+1/2y)^2 b, (1/3x-2y)^2 c, (x+5).(x-5) d, (4x-3).(4x+3) CTLHN luôn @@, hướng dẫn giải giúp em 3x+2y=14 Medium Solution Verified by Toppr The given equation is 4x−y=4 and 3x+2y=14 Now, let us find atleast two solutions of each of the above equations, as shown in the following tables.
