Answer:
X=21
Step-by-step explanation:
Change the fraction of 3 1/2 to improper fraction of 7/2
Therefore multiply both sides by 2 as it is the denominator on the right hand side
Therefore you'll have 2x/6 = 7, then multiple both sides by 6 as it is a denominator on the left hand side
Therefore you divide both sides by 2 so that x is left as a subject of the equation........ x=42/2
Therefore x=21
