Solve for x: two thirds plus one third times x equals two times x
Salsk061 [2.6K]

Answer:  x = 2/5 in fraction form

In decimal form, the answer is x = 0.4

====================================================

Work Shown:

2/3 = two thirds

2/3 + (1/3)x = 2x  is the equation you're given

Multiply every term by 3 so that we clear out the fractions

3*(2/3) + 3*(1/3)x = 3*2x

2 + x = 6x

From here, we solve for x

2 + x = 6x

2+x-x = 6x-x .... subtract x from both sides

2 = 5x

5x = 2

5x/5 = 2/5 ... divide both sides by 5

x = 2/5

x = 0.4

Will mark brainliest:) helppppp -7x + y = -19 -2x+ 3y = -19 solve the system of equations
Luba_88 [7]

Answer:

X=2, Y=-15

Step-by-step explanation:

-7x+y=-19

-2x+3y=-19

------------------

-3(-7x+y)=-19

   -2x+3y=-19

---------------------

21x-3y=57

-2x+3y=-19

---------------------

19x     = 38

19x/19=38/19

x=2

now plug 2 into x of the second equation to get y=-15

Solve for x.3-sqrt(x)=0 What is the root? If there is none, choose none. x = 3 x = 9 none
Kryger [21]

Answer:

9

Step-by-step explanation:

3-sqrt(x)=0 should be rewritten as 3 = sqrt(x) or sqrt(x) = 3.

To obtain the value of x that satisfies this equation, square both sides:

x = 3^2, or x = 9.
