suppose
Let ... be ...
Both will do.
The solution is generally solution, and the idiom is abbreviated as soln.
∫ax+by+c = 0
∴3a-b+c=0
{ -2a+b+c=0
Therefore, 5a=2b, a=-2c and b=-5c.
A: y=-2x/5+ 1/5.
Property 1
Adding (or subtracting) the same algebraic expression on both sides of the equation still holds.
If a=b
Then a+c=b+c
Attribute 2
When both sides of the equation are multiplied or divided by the same non-zero algebraic expression, the equation still holds.
If a=b
Then there is a c = b c
Or a÷c=b÷c (c≠0).
