Answer:
x = 3
Step-by-step explanation:
(25x)° = (22x + 9)° Divide each side by 1°
25x = 22x + 9 Subtract 22x from each side
3x = 9 Divide each side by 3
<em>Check: </em>
(25× 3)° = (22×3 + 9)°
75° = (66 + 9)°
75° = 75°
x = 2/7
isolate the variable by dividing each side by factors that don't contain the variable
