Step: Solve x = −2 for x:

x = −2

Step: Substitute −2 for x in 3x + y = 8:

3x+y=8

(3)(−2)+y=8

y−6=8(Simplify both sides of the equation)

y−6=8 (Add 6 to both sides)
+6 +6

y = 14

Answer:
x = −2
and
y = 14

Find the value of y when x=0 using the equation y=-2/3x +4. Explain

bixtya [17]

Given :-

y = 2/3x + 4 .

To Find :-

The value of y when x = 0 .

Solution :-

The given equation to us is ,

$\longrightarrow$ y = -2/3x + 4

So when we substitute x = 0 , we have ,

$\longrightarrow$ y = -2/3 *0 +4

$\longrightarrow$ y = 0 + 4

$\longrightarrow$ y = 4

Hence the required answer is 4.

Answer:

c. $\frac{3x + 4}{x^2}$

Step-by-step explanation:

Given:

$\frac{3}{x} + \frac{4}{x^2}$

Required:

The sum

Solution:

$\frac{3}{x} + \frac{4}{x^2}$

Common denominator is x².

Therefore, divide x² by the denominator of each fraction and multiply by each of its denominator.

Thus, we would have:

$\frac{3x + 4}{x^2}$
