x be the age of Marcus

Then according to the questions

Yolanda's Age "2x-5"

It is also given that Yolanda's age is 15 years,

2x = 15+5

2x=20

x = 20/2

x=10

So, Marcus's age is 10 ..

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
