Divide by 5 each side
X+2=4
Subtract 2 from each side
X=2

5(2+2)=20
Does work


In algebra when isolating (leaving alone on one side) x, you do the opposite operation, thus multiplying when you are trying to get rid of a division and vice versa

Terryn has 25 one-dollar bills and wants to give an even amount to each of his two children. How many bills do each of Terryn's
aleksley [76]

Answer:

Number of one-dollar bills each child gets: 12 dollars

Dollars left over: 1 dollar

Step-by-step explanation:

25/2=12.5

so round down to 12 cause 13(2) is 26 and you only have 25.

so 12(2)=24.

Each kid will get 12 dollars and there will be 1 dollar left over.

Vikentia [17]

Answer:

No solution

Option 4 is correct

Step-by-step explanation:

Given: The system of inequality

y>\dfrac{3}{2}x-1

y

We need to choose correct option.

Option 1: (-5,2)

Put x=-5 and y=2

Equation 1                               Equation 2

2>\dfrac{3}{2}(-5)-1                            2

2>-8.5                                    2

    TRUE                                     FALSE

Option 2: (2,2)

Put x=2 and y=2

Equation 1                              Equation 2

2>\dfrac{3}{2}(2)-1                    2

2>2                                           2

  FALSE                                      FALSE

Option 3: (5,2)

Put x=-5 and y=2

Equation 1                            Equation 2

2>\dfrac{3}{2}(5)-1                      2

2>6.5                                           2

 FALSE                                      TRUE

Option 1, 2 and 3 are incorrect because both equation must be true for solution.

Hence, Option 4 is correct no solution.
