Please help ASAP! Fake answers will be reported. What is the resulting equation when the expression for y in the second equation is substituted into the first equation?
3x + y = 1
y = 3 - 4x

-x + 6 = 1 is the resulting equation when the expression for y in the second equation is substituted into the first equation 3x + y = 1 y = 6 - 4x . 5x = 10 is the result of adding the system of equations: 2x + y = 4 3x - y = 6 .Step-by-step explanation:

mark brainiest

the ans is -5 hope it may help u

Step-by-step explanation:

first 3x +y =1

y = -3x +1

putting the value of y in other equation

y=3-4x

-3x+1 = 3 -4x

x = 2 putting the value of x in first equation

6 + y =1

so y =-5

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
