Let the number is x So, X+20=69 X=69-20 X=49 THE NUMBER IS 49 SO, 49 plus 20 equal to 69 .•.
x+27=43 x+27-27=43-27 x+0=16
76= -43 + X add 43 to both sides 76 + 43 = -43 + 43 + x 119 = x
2x + 15 = 8x + 43 -6x = 28 x = -6 / 28 = -3 / 14
4x + 69 = 30 + 5xSeparate the variables and constants (subtract 4x from each side):69 = 30 + xSubtract 30 from each side (your variable is already a unit) :39 = x
