What is the solution to the system of equations?

3x+y=4

2x+y=4

A. (-3, 13)

B. (-3, 12)

C. (-1, 7)

D. (0, 4)

3x+y=2x+y because 4=4

x=0 because 3x-2x=1x or x and y-y=0

now substitute 0 for x to get y and y=4

the answer is D

Since 3x3⁢x does not contain the variable to solve for, move it to the right side of the equation by subtracting 3x3⁢x from both sides. y=-3x-4y=-3⁢x-4Use the slope-intercept form to find the slope and y-intercept. Tap for more steps ... Slope: - 3-3Y-Intercept: - 4

Multiply - 1 - 1 by - 2 - 2 to get 2 2. Multiply 4 4 by - 1 - 1 to get - 4 - 4. Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m ⁢ x + b, where m m is the slope and b b is the y-intercept.
