    Answer: y = 8.1

    Step-by-step explanation: If we’re asked to solve for y in the equation y + 2.9 = 11, what we’re really being asked to do is get y by itself on one side of the equation.

    So if we take a look at the left side of our equation, notice that 2.9 is being added to y so in order to get y by itself, we must subtract 2.9 from the left side of the equation and remember from your first rule of solving equations that if we subtract 2.9 from the left side of the equation, we must also subtract 2.9 from the right side of the equation.

    So on the left side our +2.9 and -2.9 cancel out and we’re left with y. On the right side of the equation, 11 – 2.9 simplifies to 8.1 so y = 8.1.

    Answer:

    8.1

    Step-by-step explanation:

    y + 2.9 = 11

    Subtract 2.9 from both sides.

    y + 2.9 – 2.9 = 11 – 2.9

    y = 8.1

    Answer: 8.1
