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)

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.

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
