If x =2 find the value of q in the equation 3x-4=x+q​
Effectus [21]

Step-by-step explanation:

given x=2

and the equation

3x - 4 = x + q

to find the value of q , you need to make q the subject in the equation as shown below

q= 3x-x -4

q=2x-4

but x= 2

so just substitute the value of x in the equation for the q

q = 2(2) - 4

q=4-4

q=0

therefore the value of q is 0
