Answer:
<em><u>x=−2</u></em> if i could get brainliest that would be great
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(−x+2x+1)=x−1
(3)(−x)+(3)(2x)+(3)(1)=x+−1(Distribute)
−3x+6x+3=x+−1
(−3x+6x)+(3)=x−1(Combine Like Terms)
3x+3=x−1
3x+3=x−1
Step 2: Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Step 3: Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Step 4: Divide both sides by 2.
2x/2=−4/2
x=−2
The 1st, 4th, and 7th terms make an arithmetic sequence of their own. The 4th term is the average of the 1st and 7th, so ...
(1st +7th)/2 = 4th
1st + 7th = 2×4th
1st = 2×4th - 7th
The first term is ...
2*141 - 132 = 150
Solution: Since, it’s a standard cone opening up on the positive x- axis
Therefore, x=√y2+z2
Answer:
-6
Step-by-step explanation:
Add 2x-15 to both sides to get 2x=-12 or x = -6.
Answer:
x = 6.
Step-by-step explanation:
x - y = 4
x + y = 8
2x = 12
x = 6.
6 - y = 4
-y = -2
y = 2
6 + y = 8
y = 2
Hope this helps!
