Y= x - 4<br> 5x+y=-34<br> How would I do this in steps ?
Lostsunrise [7]

Answer:

x =  -5  y = -9

Step-by-step explanation:

y = x -4

5x + y = - 34

substitute x-4 in for y to solve for x

5x + x - 4 = 34

solve for x . . . add 5x + x = 6x

so you now have 6x-4 = -34

add 4 to both sides of the equation

6x-4 + 4 = -34+ 4

6x = -30

divide both sides by 6

6x/6 = -30/6

x= -5

then you plug -5 for x in the first equation

y = x - 4

y= -5 -4

y =-9

x= -5   y=  -9
