Y = x + 7 and y = -x + 2
larisa [96]

Answer:

y = x + 7

y = (-x) + 2

X + 7 = (-x) + 2

X + X = 2 - 7

2x = (-5)

<h3>x = (-5)/2 </h3>

Putting the value of X in equation

Y = (-5/2) + 7

Y = (-5)/2 + 7/1

Equalising the denominator by Taking LCM

Y = (-5)/2 +14/2

Y = ( -5 +14)/2

<h3>Y = (9)/2 </h3>

-7x - 2y = 19<br> 4x + y = -12<br> Solve the system
nalin [4]

-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)
