21) 3(2j-k)=108 It is asking you to set the equation equal to j
distribute the 3
6j-3k=108
move k to the other side by adding on both sides
6j=108+3k
divide everything by 6
j=18+0.5k
Answer:
for -11, 28. for 11, -38
Step-by-step explanation:
Typos in your question. can't tell if you need -11 or pos 11
-3(-11)-5 = 33-5= 28
-3(11)-5 = -33-5 = -38
Answer:
7

Answer:
In Heather's solution to the problem, she wrote and solved an equation.
Her work is:
Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87
Solving like terms
1.08(x+15}=21.87
dividing both side by 1.08
we get
x+15=21.87/1.08
x+15=20.25
subtracting both side by 13.9198
x=20.25-15
x=5.25
According to correction
;
<u>Option </u><u>1</u><u>st</u>
<u>yes,it is correct.</u>
7x + 5 = 2x - 35
=> 7x - 2x = - 35 - 5
=> x( 7 - 2 ) = - ( 35 + 5 )
=> x( 5 ) = - ( 40 )
=> x × 5 = - 40

x = 5
Therefore the value of x in the given equation 5
