suppose

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).
