 Jesak of Edo This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

Equation Y*2+5*Y=3+4(Y+3)

Simplifying
Y * 2 + 5Y = 3 + 4(Y + 3)

Reorder the terms for easier multiplication:
2Y + 5Y = 3 + 4(Y + 3)

Combine like terms: 2Y + 5Y = 7Y
7Y = 3 + 4(Y + 3)

Reorder the terms:
7Y = 3 + 4(3 + Y)
7Y = 3 + (3 * 4 + Y * 4)
7Y = 3 + (12 + 4Y)

Combine like terms: 3 + 12 = 15
7Y = 15 + 4Y

Solving
7Y = 15 + 4Y

Move all terms containing Y to the left, all other terms to the right.

Add '-4Y' to each side of the equation.
7Y + -4Y = 15 + 4Y + -4Y

Combine like terms: 7Y + -4Y = 3Y
3Y = 15 + 4Y + -4Y

Combine like terms: 4Y + -4Y = 0
3Y = 15 + 0
3Y = 15

Divide each side by '3'.
Y = 5

Simplifying
Y = 5
