Answer:
x =7
Step-by-step explanation:
Solve for x:
5 x - 10 + 65 = 90
Add like terms. 65 - 10 = 55:
5 x + 55 = 90
Subtract 55 from both sides:
5 x + (55 - 55) = 90 - 55
55 - 55 = 0:
5 x = 90 - 55
90 - 55 = 35:
5 x = 35
Divide both sides of 5 x = 35 by 5:
(5 x)/5 = 35/5
5/5 = 1:
x = 35/5
The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:
Answer: x = 7
4(x-1)=1/2(x-8)
First, distribute.
4x-4=1/2x-4
Subtract 1/2x from both sides.
7/2x-4=-4
Add 4 to both sides.
7/2x=0
Divide both sides by 7/2.
x=0
The answer is x=0.
Hope this helps :)
