How to work -1x-2y=-13 x-2y=11 equation by substitution

Norma-Jean [14]

Well if you're wanting to use substitution, you first have to end up with one term on either side of the equation. Use the second one as it's easiest.

So: x-2y=11, so find -2y as there is a -2y in the first equation.
then that becomes -2y=11-x. then sub that into equation 1, and you get:

-x+11-x=-13, which equals to -2x+11=-13, which is -2x=-24, so therefore

x=12. then chuck the x into any of the equations to find what y equals.

hope this helps!

Which value or in the solution set of the inequality − 2/3 x + 13 ≥ − 1

Svetach [21]

Answer:

x $\leq$ 21

Step-by-step explanation:

(-2/3)x+13≥ -1

(-2/3)x≥ -14 (I subtracted by 13 on both sides)

x $\leq$ -14*(-3/2) (I divided by -2/3 on both sides)

x $\leq$ 21

Given 16 = −5 + z4solve for z

AysviL [449]

Hi,

$16 = - 5 + z4 \\ - 4z + 16 = - 5 \\ - 4z = - 5 - 16 \\ - 4z = -21$

Now just divide both sides of equation by -4.

$z = \frac{21}{4}$

Simplify:

$z = 5 \frac{1}{4} \: \: \: \: \: \: \: \: \: \: \: \: \: fraction \: result$

Decimal form:

$z = 5.25 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: decimal \: result$

Hope this helps.
