If 11 + X = 77, X = 66. What you have to do is 77 - 66, and that = 11!
.5 X.66 =.33 .66 X .5 = .33 .33 / .5 = .66 .33 / .66 = .5 I don't know if the division part is right. :(
x = 66/92 = 0.7174
66 x 6 = 396
Add everything up on the left side first: 52 + 90 + (-76) + x = 66 + x 66 + x = 360 Now just subtract 66 from both sides: 66 + x - 66 = 360 - 66 x = 294
