2, 4, 6 and 8 respectively
let the no be x then, 4x=36+ (-2x) 4x+2x =36 6x = 36 x =6
If 4x + 4 = 2x + 36 then:4x - 2x = 36 - 4 (we have moved the "x's" all to one side and the constants [the numbers] to the other side; remember we must reverse the sign, e.g. change a plus to a minus, when moving something from one side of the equation to the other).We can now simplify this to:2x = 32Therefore:x = 32/2x = 16.
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
-2x=-4x*24 x=12
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
If 4x-2 equals 2x-34 then x is equal to -16. 4x is equal to 2x-322x is equal to -32x is therefore -16
let the no be x then, 4x=36+ (-2x) 4x+2x =36 6x = 36 x =6
5 - 2x = 16 - 4x ie 4x - 2x = 16 - 5 ie 2x = 11 ie x = 5.5 Check: does 5 - 11 = 16 - 22? Yes, both = -6.
If 4x + 4 = 2x + 36 then:4x - 2x = 36 - 4 (we have moved the "x's" all to one side and the constants [the numbers] to the other side; remember we must reverse the sign, e.g. change a plus to a minus, when moving something from one side of the equation to the other).We can now simplify this to:2x = 32Therefore:x = 32/2x = 16.
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
-4x=2y-16 +16 +16 (-4x+16)=(2y) /2 /2 y=-2x+8
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
-2x=-4x*24 x=12

4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
