-13 - (-9)
-13 + 9
= -4
Answer:
x = -4
Step-by-step explanation:
Step 1: Write equation
-x + 3 = 7
Step 2: Solve for <em>x</em>
- Subtract 3 on both sides: -x = 4
- Divide both sides by -1: x = -4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-(-4) + 3 = 7
4 + 3 = 7
7 = 7
Answer:
The above system of equation have NO INTERSECTION POINT.
Step-by-step explanation:
Here, the givens system of equation are:
-3 x + 3 y = 4
and y = x + 3
Now, for the intersection of the equations:
Put y = x + 3 in the given first equation:
-3 x + 3 y = 4 ⇒ -3x + 3 (x+ 3) = 4
or, - 3x + 3x + 9 = 4
⇒ 9 = 4 which gives A CONTRADICTION as 9 ≠ 4
Hence, the above system of equation have NO INTERSECTION POINT.
-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2
Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1
3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3
