Question

What is the value of y in the solution to the following system of equations?

4x − 3y = 12
x + 2y = 14 can you show me the steps of doing this

Answer 1

label the equations.... (1) and (2)

4x - 3y = 12 (1)

x + 2y = 14 (2)

The process is to eliminate 1 letter... multiply equation 2 by 4 and then suntract from equation 1


4 x - 3y = 12
- (4x + 8y = 56)
- 11y = -44
y = 4

sub into either equation to get x = 6
