Answer:

y=-27

Step-by-step explanation:

if y=-27 the equation will look like this:

-3-(-27)=24

to solve the LHS of the equation, we need to find what -3-(-27) is

we know that two negatives make a positive so that changes the equation to:

-3+27

we can rearrange the equation to the following:

27-3=24

Now fully simplify the equation:

24=24

The y value is correct

The answer is a = $\frac{4}{-3}$

Step-by-step explanation:

1. Convert the mixed fraction to an improper fraction

To find the numerator, multiply the denominator by the whole number and add the numerator to it.

The denominator remains the same.

So, 2 $\frac{2}{3}$ will be $\frac{8}{3}$

2. Now the equation is,

$\frac{3}{2}$ a - $\frac{4}{3}$ a = $\frac{10}{3}$ + $\frac{8}{3}$ a

3. Take LCM on both sides.

For the left side, multiply the first fraction by $\frac{3}{3}$ and multiply the second fraction by $\frac{2}{2}$

$\frac{3*3}{2*3}$ a - $\frac{4*3}{3*3}$ a = $\frac{10+8a}{3}$

4. Solve by making a the subject

$\frac{9a-8a}{6}$ = $\frac{10+8a}{3}$

$\frac{a}{6}$ = $\frac{10+8a}{3}$

$\frac{3a}{6}$ =10+8a

$\frac{a}{2}$ = 10 + 8a

a = 2(10 + 8a)

a = 20 + 16a

a-16a = 20

-15a = 20

a = $\frac{20}{-15}$

a = $\frac{4}{-3}$

Therefore, the answer is a = $\frac{4}{-3}$

three times a number is three more than twice the number which equation can be used to find the value of X the unknown number

Lyrx [107]

Let the value of the number be represented as x.

Then, write out an equation;

3x=2x+3 <--- Solve for x now
3x-2x=3
x=3

Therefore the number is 3.

Hope I helped :)
