(3y-1) by 4+(2y+3) by 3=(1-7y) by 6 verify
Answers
Answer:
3(2y + 3) + 6(3y + -1) = 1 + -7y
Reorder the terms:
3(3 + 2y) + 6(3y + -1) = 1 + -7y
(3 * 3 + 2y * 3) + 6(3y + -1) = 1 + -7y
(9 + 6y) + 6(3y + -1) = 1 + -7y
Reorder the terms:
9 + 6y + 6(-1 + 3y) = 1 + -7y
9 + 6y + (-1 * 6 + 3y * 6) = 1 + -7y
9 + 6y + (-6 + 18y) = 1 + -7y
Reorder the terms:
9 + -6 + 6y + 18y = 1 + -7y
Combine like terms: 9 + -6 = 3
3 + 6y + 18y = 1 + -7y
Combine like terms: 6y + 18y = 24y
3 + 24y = 1 + -7y
Solving
3 + 24y = 1 + -7y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '7y' to each side of the equation.
3 + 24y + 7y = 1 + -7y + 7y
Combine like terms: 24y + 7y = 31y
3 + 31y = 1 + -7y + 7y
Combine like terms: -7y + 7y = 0
3 + 31y = 1 + 0
3 + 31y = 1
Add '-3' to each side of the equation.
3 + -3 + 31y = 1 + -3
Combine like terms: 3 + -3 = 0
0 + 31y = 1 + -3
31y = 1 + -3
Combine like terms: 1 + -3 = -2
31y = -2
Divide each side by '31'.
y = -0.06451612903
Simplifying
y = -0.0645161290
