Question 1)Solve 8x + 3 = 3x + 18
2 answers:
Step-by-step explanation:
8x-3x = 18-3(like terms)
or,5x = 15
or,x=15/5
or,x=3
Answer:
x = 3
Step-by-step explanation:
in order to solve for the value of x in the expression
8x + 3 = 3x + 18
we are going to simply combine the like terms then later evaluate for the value of x
8x + 3 = 3x + 18
8x + 3 - 3x = 18
8x -3x = 18 -3
5x = 15
divide both sides by the coefficient of x
5x/5 = 15/5
x = 3
therefore the value of x in the expression
8x + 3 = 3x + 18 is equals to 3
