Answer:
Step-by-step explanation:
1) Expand by distributing terms.
2) Simplify 4*3x to 12x.
3) Simplify 4*2y to 8y.
<u>Therefor, the answer is </u><u>12x + 8y.</u>
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
Answer:
84
Step-by-step explanation:
Answer:
136
Step-by-step explanation:
The absolute value function always returns a positive value , that is
| - a | = | a | = a
Then
| - 136 | = | 136 | = 136
Answer:
-4
Step-by-step explanation:
If there is 1-5 then we should do – from last I mean we should do -5-1 you will not understand like this I will show you by sep wise step
= -5
-1
————
ans -4
If you will not understand Look here when there will be -5-4 then what should we do? There is -5-4 So we should do –
If there is -4+2 then you don't know how to do it. So note this: + × + = +
+ × - = -
- × + = -
I know this much only. If you have more doubt then ask for your Maths teacher.
