Question

I have 3 questions for math

1. Two lines have the given equations. Use the Linear Combination Method to solve. (see the link for solving this one)

2. Solve the system of equations using the Substitution Method

4x+2y = 10
y = 4x + 2

3. Solve the system of equations using any method

6x – y = 2
y = 3x + 4

Answer 1

1. no question content
2. (x, y) = (1/2, 4)
3. (x, y) = (2, 10)

Explanation:

1. No link, no question

__

2. Divide the first equation by 2 and substitute for y using the expression in the second equation.

2x +(4x+2) = 5

6x = 3 . . . . . . . . . subtract 2

x = 3/6 = 1/2 . . . . divide by2

y = 4(1/2) +2 = 4 . . . . substitute into the equation for y

The solution is (x, y) = (1/2, 4).

3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
