Y+2 = -3(x – 4)<br> Complete the missing value in the solution to the equation. <br><br> (?, -2)

ss7ja [257]

Answer:

The missing value in the solution to

the equation will be:

$x=4$

Step-by-step explanation:

Given the equation

$y+2\:=-3\left(x\:-\:4\right)$

As the value of y = -2 is given.

so substituting the value y = -2 in the equation to find the missing value

$\left(-2\right)+2\:=-3\left(x\:-\:4\right)$

switch the sides

$-3\left(x-4\right)=\left(-2\right)+2$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$-3\left(x-4\right)=-2+2$

$-3\left(x-4\right)=0$

$\mathrm{Divide\:both\:sides\:by\:}-3$

$\frac{-3\left(x-4\right)}{-3}=\frac{0}{-3}$

$x-4=0$

$x=4$

Therefore, the missing value in the solution to

the equation will be:

$x=4$
