5X+3=23
Subtract 3 from both sies
5X=20
no devied both sides by 5
X=20/5
So
X=4

O.k. to solve an equation like this, here are the steps:
1. Not needed
2.Not needed
3.Add like terms (if possible)
4.Add the opposite (meaning if there's a subtraction sign, change it to an addition sign and vice versa)
5. Divide by coefficient ( in this case, you divide by 5)
6. Check your answer.
O.k. so first you change the sign. Change 5x+3 to 5x-3.
Then subtract 3 from your answer (23-3=20)
Now you divide by the coefficient which is 5x. (20 divided by 5 equals 4)
x=4
Now check your answer:
5x4=20 + 3= 23 Therefore, x=4

first subtract 3 from 23.
so 5x=23-3
5x=20
next, divide 20 by 5
so x=20/5
then your answer is 4.
x=4

5x + 3 = 23
Subtract 3 from both sides:
5x + 3 - 3 = 23 - 3
5x = 20
Divide both sides by 5:
(5x)/5 = (20)/5
x = 4

Minus 3 from both sides--> 5x = 20
Then, divide both sides by 5--> x = 4

subtract three from both sides giving you the equation
5x=20
then divide both sides of the equation by 5
giving you the answer x=4
