2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7
Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
x = 64 64 + 64 = 128
x = 116. x + 64 = 180 is the same as x = 180 - 64, which equals 116.
x + 30 = 64 Therefore, x = 64 - 30 x = 34
a=64 b=8 (x+16x+64)=(x+8)^2
find x when, 2x=128 2x=128 /2 /2 x=128 /2 x=64 then check your answer by doing the following if x=64, then what is 2x? 2(64)=? or 2 * 64=? or 2 x 64=? 2 times 64 equals 128!
The answer is 64.

57 + 7 = 64
64 + 27 = 91
162+64=226
x = 64 64 + 64 = 128
