Answer:
k = -1/240
Step-by-step explanation:
to evaluate the value of k in the expression 1/3k+80=1/2k+120
we have
1/3k+80=1/2k+120
collect the like terms for easy evaluation
1/3k - 1/2k = 120 -80
1/3k - 1/2k = 40
find the lcm
2 - 3/6k = 40
-1/ 6k = 40
cross multiply
6k x 40 = -1
240k = -1
divide both sides by 240
240k/240 = -1/ 240
k = -1/240
therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240
Answer:
36
Step-by-step explanation:
Break it into parts to make it easier. The equation would become 16+12+8 which is 36
<span>17x-2=7x+8
We simplify the equation to the form, which is simple to understand
<span>17x-2=7x+8
We move all terms containing x to the left and all other terms to the right.
<span>+17x-7x=+8+2
We simplify left and right side of the equation.
<span>+10x=+10
We divide both sides of the equation by 10 to get x.
<span>x=1</span></span></span></span></span>
