Found the figure:TU = 7TS = x - 1Since T is equidistant from u and s, this means that TU = TS7 = x - 17 + 1 = x8 = xThe ...
X-0.9 = 4.5
+0.9 +0.9
x = 5.4
( to get rid of the -0.9 beside the x, u have to do the opposite operation on both sides. if its -0.9, u have to add 0.9 on both sides)
not sure about the first one.
8 is in the tens place. It has a value of 80.
