solve for (isolate) x. x+ab=ax+3. please show step by step, help me!?

Question

i cant get it ! please show step by step, such as
5(2+1)
10+5
15

Thank You!

Answer 1

x+ab=ax+3
x-ax=3-ab
x(1-a)=3-ab
x=(3-ab)/(1-a)

Answer 2

x + ab = ax + 3

What you want to do is move everything that has an x in it to the left hand side, and everything else to the right hand side. I'll do this in steps so I can be clear.

First, I'll move the ab to the right hand side. This of course becomes -ab.

x = ax + 3 - ab

Next, we move ax to the left hand side. As a result, ax will become -ax.

x - ax = 3 - ab

Now, we *factor* x out of the terms on the left hand side.

x(1 - a) = 3 - ab

Since we want to isolate the x, we *divide* both sides by (1 - a). This gives us

x = (3 - ab) / (1 - a)

Answer 3

Solve for "x" > x + ab = ax + 3...

First: combine the x-variables > subtract "ax" from both sides...

x + ab - ax = ax - ax + 3

x + ab - ax = 3

Sec: subtract "ab" from both sides...

x + ab - ab - ax = 3 - ab

x - ax = 3 - ab

Third: factor the left side > find the common factor...

x(1 - a) = 3 - ab

Fourth: isolate "x" on one side > divide both sides by "1-a"...

[x(1 - a)]/1-a = (3 - ab)/1-a

*Cross cancel "like" terms...

x = (3 - ab)/1-a

Answer 4

x + ab = ax + 3
x + ab -3 = ax (move all non-x terms to other side)
ab - 3 = ax - x (move all x terms to same side)
ab - 3 = (a-1)x (factor the x out of all terms on the x side)
(ab-3)/(a-1) = x (divide by a-1 to isolate x)

Answer 5

0. Recopy the equation: |---: x + ab = ax + 3. a million. positioned each and every of the x words on area and each and everything else on the different: |---: x - ax = 3 - ab. 2. team each and every of the x words into one expression: |---: x (a million-a) = 3 - ab. 3. Divide each and every area through regardless of is encumbering the x: |---: x = (3-ab) / (a million-a).

Answer 6

X+ab=ax+3
subtract x from left to move to right, subtrat 3 from right to move to left
ab-3=ax-x.....factor out x
ab-3=X(a-1)....divide by (a-1)
get X=(ab-3)/(a-1)

Answer 7

x+ab=ax+3

x+ab-ax=3 (subtract ax for both sides)
x-ax= 3-ab (subtract ab for both sides)
x(1-a)=3-ab (take out x)
x= (3-ab)/(1-a) (divide 1-a for both sides)

the second equation, you got it right.

or you calculate in side the parethsis fist
5(3)
15

Answer 8

what the first 2 said constance

Answer 9

No.
