Hint:
try to send each part on l.h.s. to r.h.s.
except y so you get y .
The correct answer is: ![y equals fraction numerator 18 plus 3 x over denominator 6 end fraction](data:image/png;base64,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)
Given
-3x + 6y = 18
step 1 :
send -3x to rhs so it becomes +3x
6y = 18 + 3x
step 2 :
now 6 is in multiply with y when it go to rhs it become divide
y = ( 18 + 3x ) / 6
so , value of y is ( 18 + 3x ) / 6 .
Solve , equation for y .
