Question

3x+24=-11 and 7x-4y=9 are simultaneous equation find the value of Dx=?​

Answer 1

Let's solve your equation step-by-step.

$3x+24=−11</p><p></p><p></p><p>$

Subtract 24 from both sides.

$3x=−11−24$

Subtract 24 from −11 to get −35.

$3x=−35$

Divide both sides by 3.

$\huge \: x = - \frac{ - 35}{3}$

Let's solve your equation step-by-step.

$7x-4y=9</p><p></p><p>$

Add 4y to both sides.

$7x=9+4y$

The equation is in standard form.

$7x=4y+9$

Divide both sides by 7.

$\huge \: \frac{7x}{7} = \frac{4y+9}{7}$

Dividing by 7 undoes the multiplication by 7.

$\huge \: x = \frac{4y+9}{7}$
