Answer:
x=1.5 y=-0.5
Step-by-step explanation:
first we want to rearrange one of the equations
we will rearrange 3x+y=4 we will do this by subtracting 3x from both sides
y= -3x+4
and replace y in the second equation 5x-7y=11
5x -7(-3x+4)=11
we will distribute -7
5x+21x-28=11
solve for x
26x=39
x=1.5
and solve y by substituting x into one of the equations
y= -3(1.5)+4
y=-0.5
