Answer:
x₁ = -1
x₂ = 5/6
Step-by-step explanation:
The equations of the given linear system are:
Multiply the first equation by -2 and add it to the second one to solve for x₁:
Since we already know the value of x₁, simply replace it in the first equation to solve for x₂:
The solution for the system is x₁ = -1 and x₂ = 5/6
Answer:
x = 7/3
Step-by-step explanation:
Factors of 9 are:
3x3
9x1
Factors of 49 are:
7x7
49x1
Only 3x3 and 7x7 equal 42 when you expand it out (3x - 7)(3x - 7) = 0
x = 7/3
