Question

Find the value of' m' if (-m 3) is the solution of equation 4x +9y -3=0

Answer 1

• (-m,3) is a solution .
• Put in equation

`\\ \qquad\quad\sf\longmapsto 4x+9y-3=0`

`\\ \qquad\quad\sf\longmapsto 4(-m)+9(3)-3=0`

`\\ \qquad\quad\sf\longmapsto -4m+27-3=0`

`\\ \qquad\quad\sf\longmapsto -4m+24=0`

`\\ \qquad\quad\sf\longmapsto -4m=-24`

`\\ \qquad\quad\sf\longmapsto m=(-24)/(-4)`

`\\ \qquad\quad\sf\longmapsto m=6`
