Answer:

x = $\frac{16+b-4a}{4}$

Step-by-step explanation:

4(a + x) - b = 16 ( add b to both sides )

4(a + x) = 16 + b ← distribute parenthesis on left side

4a + 4x = 16 + b ( subtract 4a from both sides )

4x = 16 + b - 4a ( divide both sides by 4 )

x = $\frac{16+b-4a}{4}$

WARRIOR [948]

Answer:

Step-by-step explanation:

From the question given above, the following data were obtained:

1 = 1

2 = 4

3 = 9

4 =?

Observing the data, we can see that the numbers on the right side are simple the squares of the numbers on the left side. This is illustrated below:

1 = 1² = 1

2 = 2² = 4

3 = 3² = 9

Thus, we shall use the same logic to obtain that of 4. This is illustrated below:

4 = 4² = 16

Thus the answer to the question is 16.
