x=7
9a + 4a = 26 13a = 26 a = 26/13 a = 2
x=7
-18
first add across 6.5x=26 then divide x=-26/6.5
-20 = -4x +6 add 20 to both sides 0 = -4x +26 4x = 26 x = 26/4 = 6.5
that is supposes to be 18 to the 6x power
One half X = 13 Double both sides: A whole X = 26 So, answer: X = 26
5t - 9 = 26(Add 9 to both sides)5t = 35(Divide both sides by 5)t = 7
11 So: x = 37
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
the answer is -11+x=26 -11+x+11=26+11 -11and +11 will be cut therefore x=37
