Question

3²(x+14)-5²=5.2²

Answer 1

3²(x + 14) - 5² = 5 . 2²

\(\Rightarrow\) 9x + 9 . 14 - 25 = 5 . 4

\(\Rightarrow\) 9x + 126 - 25 = 20

\(\Rightarrow\) 9x + 126 = 45

\(\Rightarrow\) 9x = -81

\(\Rightarrow\) x = -9

Answer 2

3²(x+14)-5²=5.2²

9(x+14)-25=5.4

9(x+14)-25=20

9(x+14) =20+25

9(x+14) =45

x+14 =45:9

x+14 =5

x =5-14

x =-9
