Answer:
change the 2w value
Explanation:
first, check the equation:
14w + 21 = 14w + 20
when subtracting the 14w from both sides you can see that
21 is NOT EQUAL to 20, making the answer NS.
now, reread the question... create a new equation with ONE solution.
to fix this, we need to change the amount of W's, NOT the amount of constant.
let's try out another number in place of 2w
7 ( 3w + 3 ) = 14w + 20
21 w + 21 = 14w + 20
7 w = -1
w = -1/7
so now it is clear. to change the outcome of the equation, try out another value instead of 2w. Maybe try 3w, 3.5w, or maybe even 1w, or 1.5w .
