|
Given the system of equations, what's the first step needed to solve?
3x + 2y = 5 4x - 6y = 2 |
Multiply the top equation by 3. This will cancel out the y's. |
|
|
Given the system of equations, what's the first step needed to solve?
-4x + 2y = 6 -4x - 3y = 3 |
Multiply one of the equations by -1. |
|
|
Given the system of equations, what's the first step needed to solve?
2x + 2y = 2 3x + 5y = 5 |
You have a choice.
A. Multiply the first equation by -3 and second equation by 2.
or
B. Multiply the first equation by -5 and the second equation by 2. |
|
|
Given the system of equations, what's the first step needed to solve?
x + y = 6 2x + 4y = 3 |
You have a choice.
A. Multiply the first equation by -2
or
B. Multiply the first equation by -4 |
|
|
When x = 5, solve for y.
3x + 2y = 5
|
y = -5 |
|
|
When x = -2, solve for y.
-4x - 3y = 5
|
y = 1 |
|
|
Find the slope.
(-3,1) (2,5) |
m = 4/5 |
|
|
Find the slope.
(2,1) (-4,-3) |
m = 2/3 |
|
|
Find the slope.
(-1,-2) (-3,-4) |
m = 1 |
|
What is the first step to solving this equation? |
Subtract 6 from both sides. |
|
What is the first step to solving this problem? |
Multiply by the reciprocal. Yes, that is really two steps! So if you said, flip the second fraction, that is OK. |
