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>
Answer:
10+8x=y
Step-by-step explanation:
The 10$ is added on because it's a one time exchange and the 8 is multiplied by the x because for every hour you add 8$ to the price and y is the total price at the end depending on x.
-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! ;)
