Solve the following system of equations

y=5x+4
y=x2+3x-4

 the following system of equations  has 2 solutions

x1=4

X2=-2

Step-by-step explanation:

5*x+4=x²+3*x-4

x²-2*x-8=0

x12=(2+/-√4+4*1*8)/2

x12=(2+/-√36)/2

x1=(2+6)/2=4

x2=(2-6)/2=-2

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
