Solve for x:
Add 4.3x on both sides so that the variable can be on one side.
9.6x - 15.4 = -4.3x + 26.3
+4.3x +4.3x
Add 15.4 on both sides so that the whole number stays on one side separate from the variable.
13.9x - 15.4 = 26.3
+15.4 +15.4
Divide both sides by 13.9.
13.9x = 41.7
------- -----
13.9 13.9
Now you get a solution of:
x = 3
Check:
9.6(3) - 15.4 = -4.3(3) + 26.3
28.8 - 15.4 = -12.9 + 26.3
13.4 = 13.4
