Solve the system of equations

Question

{ y = 2.0.82 y = -0.7x +3
What are the x coordinates of the solutions (rounded to two decimal places)?
X 1.2 and x = 7.8
x = 2.57 and y = 7.8
x= -6.86 and x = 2.57
x = -6.86
X 1.2

Answer 1

The system of equations provided is:

y = 2
y = -0.7x + 3

Since y = 2 in the first equation, we can substitute y = 2 into the second equation:

2 = -0.7x + 3
-0.7x = 1
x = -1.43

Therefore, the x coordinate of the solution is x = -1.43 (rounded to two decimal places).
