Ax+by=c, how would I solve for y

Answers

Answer 1

Answer: Solving for y means trying to get the equation into the form y= _____. So, let's say that we are going to keep the y value on the left side of the equation.

First, we would subtract ax from both sides. This results in the equation by=c-ax.

Next, we figure out that y has a coefficient of b. They are combined together by multiplication, so to undo this operation, we need to divide both sides by b.

If done correctly, your final answer should be $(c-ax)/(b)$ . Or, y=c-ax/b

Answer: $v=(5)/(2)$

Step-by-step explanation:

First, substitute the variables with the given values.

$v=u+at$ turns into $v=1+(3)((1)/(2) )$

First, multiply what is in the parentheses

$(3)((1)/(2))=(3)/(2)$

$v=1+(3)/(2)$

Turn 1 into a fraction over 2 by multiplying 1 by 2 and using it as the numerator

$1=(2)/(2)$

$v=(2)/(2) +(3)/(2)$

Add

$v=(5)/(2)$

c){-15,27}
d){-21,33}

Answers

If you would like to solve x^2 - 12 * x = 13, you can do this using the following steps:

x^2 - 12 * x = 13
x^2 - 12 * x - 13 = 0
(x - 13) * (x + 1) = 0
1. x = 13
2. x = -1

The correct result would be b) {-1, 13}.
