Question

The present ages of Anju and Manju are x and y. The sum of their ages five years ago is 42.Frame an equation and plot the graph.. answer fastt

Answer 1

Answer:

Present age of Anju=x years

Present age of Manju=y years

Five years ago,

age of Anju=(x-5) years

age of Manju= (y-5) years

GIVEN: Sum of the ages five years ago is 42.

$(x-5)+(y-5)=42\\x+y-10=42\\x+y=52$

To plot a graph, put a few value of the x in the above equation and find the values of y. when x=30, y=22 and when x=40,y=12. So (30,22) and (40,12) are solutions of this equation.

$\left[\begin{array}{ccc}x&30&40\\y&22&12\\\end{array}\right]$

Plot these points on the graph and join them with a line with ↔ as the end and start symbols.
