X + 2 = 5x + 26<br><br> Please help
kkurt [141]
x+2=5x+26

Move all the x's to one side of the equation. This is a step necessary to solve this equation.

Subtract both sides by x.

x+2-x=5x+26-x
2=4x+26

Flip equation. We always want to have the variable written on the left side.

4x+26=2

Subtract both sides by 26.

4x+26-26=2-26
4x=-24

Divide both sides by 4 to finish this off.

x=-6

That's your answer. Have an awesome day! :)

Find all solutions of the given system of equations and check your answer graphically. HINT [See Examples 2–5.] (If there is no
Reika [66]

The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, If the given equation is x-y=0 and x+y=8.

Step-by-step explanation:

The given is,

                              x-y=0...............................(1)

                              x+y=8...............................(2)

Step:1

          Solution can be obtained by Elimination method,

          Equation (1) is multiplied by (-1)           ( Eqn (1) × -1 )

                             -x+y=0..............................(3)

          Substrate the equation (1) and equation (3),

                              -x+y=0

                                x+y=8

         ( - )

         (-x-x)+(y-y)=(0-8)

                             (-2x)=-8

                                -2x = -8

         we can cancel the minus because it is available in both sides,

                                  2x=8

                                    x = \frac{8}{2}

                                     x = 4

        From the value of x, Equation (2) becomes,

                              x+y=8

                               4+y=8

                                     y = 8-x    (Value of y in terms of x)

        Where, x = 4

                                     y = 8-4        

                                     y =4

Step:2

       Check for solution,

                             x+y=8.....................................(2)

       Substitute the values of x and y,

                             4 + 4 = 8

                                   8 = 8

Result:

         The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, where x=4. If the given equation is x-y=0 and x+y=8.
