Answer:

The value of x is -5/3.

The value of 1/3 - x is 2.

Step-by-step explanation:

-3( x+2)-5=x-(6+x) Distribute

-3x + -6 - 5 = x - 6 - x Combine llike terms

-3x + -11 = -6 POSITIVE AND NEGATIVE IS NEGATIVE

-3x -11 = -6 Add 11 on both sides

-3x = 5 Isolate the variable by dividing -3 on both sides

x = -5/3

1/3 - x

= 1/3 - -5/3 NEGATIVE AND NEGATIVE IS POSITIVE

= 1/3 + 5/3

= 6/3

= 2

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on ONLY one side of the equation.

Express the equation x = 10 and y = -3 as a linear equation in two variables

34kurt

Answer:

For x = 10:

$x + 0y - 10 = 0$

For y = - 3:

$0x + y + 3 = 0$

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

$ax + bx = c$

So first let's solve for x=10:

$x = 10$

Move 10 to the other side.

$x - 10 = 0$

As there is no y given we will simply write 0y.

$x + 0y - 10= 0$

Now let's solve for y=-3:

$y = - 3$

Move -3 to the other side.

$y + 3 = 0$

As there is no x given we will simply write 0x.

$0x + y + 3 = 0$

Question is in picture.

Norma-Jean [14]

Answer:

Step-by-step explanation:

Having the system of equations in its simplest form

$\left\{\begin{array}{ccc}ax+by=c\\dx+ey=f\end{array}\right$

$a=d,\ b=e,\ c=f$

then the system of equations has infinitely many solutions.

$a=d,\ b=e,\ c\neq f$

then the system of equations has no solution.

$a\neq d\ or\ b\neq e$

then the system of equations has one solution.

We have the equation

$y=-2x+4$

Convert to the standard form Ax + By = C:

$y=-2x+4$ add 2x to both sides

$y+2x=-2x+2x+4\\\\2x+y=4$
