Question

If (x+42)+3x = 90 what is x

Answer 1

X=12

Explanation:

First, take the term out parenthesis being careful to manage the sign of individual term carefully :

x+42+3x=90

Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :

x+42-42+3x=90-42

x+0+3x=48

x+3x=48

(1+3)x=48

4x=48

Now, Divide both side of equations by 4 to slove of x while keeping equation balance :

4x/4=48/4

x=12

Here,

(12+42)+3*12=90

54+36

90
