Answer:
p = 2
Step-by-step explanation:
Step 1: Write equation
2p + 7 = p + 9
Step 2: Subtract p on both sides
p + 7 = 9
Step 3: Subtract 7 on both sides
p = 2
Answer:
can you elabrate on that please
Step-by-step explanation:
Answer:
x= 1/2
y=3
Step-by-step explanation:
it is easier to subtract both equation and obtain a new one
1) 6x+0.4y=4.2
2) -4x+0.4y=-0.8
---------------------------------
1) -2)= 10x+0=5 leading to x=1/2
Now just eval x=1/2 in any of the original equations, for instances
1) 6*(1/2) +0.4*y=4.2, which leads to y=3
I hope this helps you, I just took this quiz so it is correct.
Answer:
6x + 1
Step-by-step explanation:
Distribute
3 + 2 ( x- 1 ) + 4x
3 + 2x - 2 + 4x
Subtract
3 + 2x - 2 + 4x
1 + 2x + 4x
Like terms
1 + 2x + 4x
1 + 6x
Rearrange
6x + 1
