Answer:
y=6
Step-by-step explanation:
use elimination by making the ys opposite in value and eliminating them from the equation so there is only variable:
-3x+2y=6
2(4x-y=2)
-3x+2y=6
8x-2y=4
Combine like terms and divide by 5 on both sides.
5x=10
x=2
Plug x in to find y:
4(2)-y=2
8-y=2
y=6
Answer:
4+4+4
Step-by-step explanation:
4^3 means 4 cubed which is equal to 4 added three time
Answer: 120
Step-by-step explanation:
5!/(5-4)!=5!/1!=(5*4*3*2*1)/1
120/1
=120
substitute the value of the variable into the equation and simplify.
the answer is 3.
