Question

What is the resulting equation when the expression for y in the second equation is substituted into the first equation?

3x + y = 1
y=6 - 4x

Answer 1

When the expression for y in the second equation is substituted into the first equation, the resulting equation is x = 5.

Step-by-step explanation:

Substituting the expression for y in the second equation into the first equation:

3x + (6 - 4x) = 1

Simplifying the equation:

-x + 6 = 1

Subtracting 6 from both sides:

-x = -5

Multiplying both sides by -1:

x = 5

So, the resulting equation is:

x = 5
