Question

Y= -x + 1 and y= 2/3x - 4 What is the solution to the system of equations?

Answer 1

x=3 /

steps: (For x)

Turn the equation into --> -x+1 = 2/3x-4

Next is the multiply the equation by 3 to make isolating x easier so it becomes --> -3x+3=2x-12

Now arrange the terms to where variables are on a side and constants are on a side

it should look like --> -3×-2x=-12-3

Now combine like terms --> -5x=-15

finally just divide by -5 on both sides

x=3

For y:

substitute X for either of the equations

y=2/3 x 3-4

y=-2

The solution is (3,-2)
