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

Answer:

Problem:

Solve 3x−y=6;y=x−4

Steps:

I will try to solve your system of equations.

y=x−4;3x−y=6

Step: Solvey=x−4for y:

Step: Substitutex−4foryin3x−y=6:

3x−y=6

3x−(x−4)=6

2x+4=6(Simplify both sides of the equation)

2x+4+−4=6+−4(Add -4 to both sides)

2x=2

2x

2

=

2

2

(Divide both sides by 2)

x=1

Step: Substitute1forxiny=x−4:

y=x−4

y=1−4

y=−3(Simplify both sides of the equation)

Answer:

y=−3 and x=1

Step-by-step explanation:

Hope this helped you
