【compare / match】
(x - 30 ) + (5x - 1) •√6
= y + 9 •√6
5x - 1 = 9 ⇨ x = (1+9)÷5 = 2
y = x - 30 = -28
Ans
x = 2
y = -28
(x - 30 ) + (5x - 1) •√6
= y + 9 •√6
5x - 1 = 9 ⇨ x = (1+9)÷5 = 2
y = x - 30 = -28
Ans
x = 2
y = -28

expand first, then compare rational numbers on LHS with rational numbers on RHS. and surd terms on LHS with surd terms on RHS.
