Answer:-3
Step-by-step explanation:
y=3x+2................(1)
y=x-4......................(11)
Subtract (11) from (1)
y-y=3x-x+2-(-4)
0=2x+2+4
0=2x+6
Collect like terms
0-6=2x
-6=2x
Divide both sides by 2
-6/2=2x/2
-3=x
x=-3
Answer:
Step-by-step explanation:2x + 9x - 9 = 16x + 16 - 5
= 11x - 9 = 16x + 11
11x - 16x = 11 + 9
5x = 20
x = 20/5
x = 4
