Question

# Is $$x=-3$$ and $$y=4$$ a solution of $$2y+3x+1=0$$

Solution

## Substituting x = -3 and y = 4 in the LHS of the equationLHS = 2y +3x +1        = 2(4) + 3(-3) +1        = 8 -9 +1        = 0        = RHSSince x = -3 and y = 4 satisfies the given equationTherefore, x = -3 and y = 4 is the  solution of the equation.Mathematics
