Solve each equation. leave the answer as an improper fraction. 16x2 = 49

Step-by-step explanation:

Solve the equation for x

To solve the equation , we need to isolate x

To get x alone , we need to remove the numbers attached with x

To remove 16 we divide both sides by 16

Now to remove square from x we take square root on both sides

square root (49) = 7

square root (16)= 4

So ,

When we take square root we include +-

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
