When solving a System of Equations where both equations are solved for the same variable, it's best to use the Substitution Method.
In the example below, which answer choice would correctly set up your equation to solve
first?
Example:
y = 4x - 6
y=-3x + 5
4x - 6 -- 3x + 5
y = x + 1
Oy - 4x - 6 - 3x + 5
44-6-3x+ 5

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39
