Solve this system of equations using elimination -3x - 4y = 7 -2x + 4y = 3

Add the two rows together

-5x = 10

Solve for x in the above equation

x = -2

Substitute x = -2 into any of the two equations. Let's pick the firs equation; -3x - 4y = 7

-3 × -2 - 4y = 7

Solve for y in the above equation

y = -1/4

Therefore,

x = -2

y = -1/4
