Make x the subject of e = bx-d

YA'LL PLEASE I CAN'T DO MATHS​

Explanation:

Your teacher wants you to isolate x.

We first undo the "minus d" by adding d to both sides. Then we divide both sides by b to undo the multiplication. In short, we follow PEMDAS in reverse undoing everything to isolate the variable.

So,

e = bx-d

e+d = bx

bx = e+d

x = (e+d)/b

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
