Question

If B, equals, y, plus, 2B=y+2 and C, equals, y, minus, 7, commaC=y−7, find an expression that equals B, plus, 2, CB+2C in standard form.

Answer 1

To find the expression B + 2C in standard form, substitute the given expressions for B and C and simplify.

Step-by-step explanation:

To find an expression that equals B + 2C in standard form, we need to substitute the given expressions for B and C into the desired expression. Given that B = y + 2B and C = y - 7, we substitute these values into B + 2C:

(y + 2B) + 2(y - 7)

Now, we simplify the expression:

y + 2B + 2y - 14

Combining like terms, we get:

3y + 2B - 14

Therefore, the expression B + 2C in standard form is 3y + 2B - 14.
