Question

3×X+50=77. 100-24÷c=92 .3×X=92-68

Answer 1

3*x+50=77
3*x=77-50
3*x=27
x=27:3
x=9

100-24:c=92
24:c=100-92
24:c=8
c=24:8
c=3



3*x=92-68
3*x=24
x=24:3
x=8

Answer 2

1) 3x=77-50
3x=77-50
3x=77
x=9
2)3x=92-68
3x=24
X=8
3)100-24/c=92
-24/c=92-100
-24/c=-8
-24=-8c
-8c=-24
C=3

Answer 3

Let's solve each equation step by step:

1. 3×X + 50 = 77

To solve for X, we'll isolate X on one side of the equation. Start by subtracting 50 from both sides:

3×X + 50 - 50 = 77 - 50

3×X = 27

Now, to find X, divide both sides by 3:

X = 27 ÷ 3

X = 9

So, the value of X in the first equation is 9.

2. 100 - 24 ÷ c = 92

Similarly, we'll isolate 'c' on one side of the equation. Begin by subtracting 100 from both sides:

100 - 24 ÷ c - 100 = 92 - 100

-24 ÷ c = -8

To solve for 'c,' divide both sides by -24:

c = -8 ÷ (-24)

c = 1/3

So, the value of 'c' in the second equation is 1/3 or approximately 0.3333.

3. 3×X = 92 - 68

Combine the terms on the right side:

3×X = 24

Now, to find X, divide both sides by 3:

X = 24 ÷ 3

X = 8

Thus, the value of X in the third equation is 8.

To summarize the solutions:

1. X = 9
2. c = 1/3 (approximately 0.3333)
3. X = 8
