The solution of the equation is  x=\frac{11}{7}

Step-by-step explanation:

To simplify an equation of x

  • Simplify each side of the equation
  • Collect x in side and the numerical terms in the other side
  • Find the value of x

∵ The equation is 2x + \frac{1-x}{4}=3

- Multiply all terms of the equation by 4 to cancel the denominator

 of the 2nd term in the left hand side

∵ The equation is 4(2x) +4 (\frac{1-x}{4})=4(3)

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ x=\frac{11}{7}

The solution of the equation is  x=\frac{11}{7}

X+y=15-2x+5y=-2 solve your systems of solutions and record your answer as an ordered pair
ipn [44]

Answer:

x = 11 and y = 4

Step-by-step explanation:

Given equations are :

x+y=15 ...(1)

-2x+5y=-2 ...(2)

We need to solve the systems of equations.

Multiply equation (1) by 2.

2x+2y=30 ...(3)

Adding equation (2) and (3).

-2x+5y+2x+2y = -2+30

7y = 28

y = 4

Put the value of y in equation (1).

x+4=15

x = 11

So, the solution of the given equations are x = 11 and y = 4.

Tonisha has a lemonade stand. She has $31 in expenses and wants to make $69 per day. If X represents the amount of revenue from
aksik [14]

Answer:

x - 31  \geq 69

Tonisha has to make at least $100 in revenue

Step-by-step explanation:

Set up the inequality:

x - 31 represents her profit

Since she wants to make at least $69 a day, use \geq 69

So, the inequality is x - 31  \geq 69

Then, solve for x to find how much she has to sell:

x - 31  \geq 69

x \geq 100

So, Tonisha has to make at least $100 in revenue
