Add $\frac{x}{2}$ to both sides:

$\dfrac{2x}{5}+\frac{x}{2} = 9$

Add the fractions in the left hand side:

$\dfrac{2x}{5}+\frac{x}{2} = \dfrac{4x}{10}+\frac{5x}{10}=\dfrac{9x}{10}$

So, the equation becomes

$\dfrac{9x}{10}= 9$

Multiply both sides by 10:

$9x = 90$

Divide both sides by 9:

$x = 10$

-6x+y=4<br> -y-2x=4<br><br> Please Solve these in <br> Y=mx+b form! I’m stuck...

il63 [147K]

Y = mx + b

1.) -6x + y = 4

Move variable x over to the other side by adding 6x.

y = 6x + 4

2.) -y - 2x = 4

Move variable x over to the other side by adding 2x.

-y = 2x + 4

Divide the whole thing by -1 because y needs to be positive and alone.

y = -2x - 4
