Monica has been saving her spare change. So far, she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25 cents), and the rest are dimes (10 cents).

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

b. x + 1
