I believe you wanted that solved? My math is down below.-

1. You have the equation, which is -5•2+2x-2=0.

2. Multiply -5•2 = -10.

3. Then, you get::-10+2x-2=0.

4. Combine the like-terms:
| -10 - -2 = -8. |

5. Combine this with the original equation.

6. -8 + 2x = 0
- 8 - 8
————————
2x. = 8
———- ——
2 2

x= 4

Show another way to write 100 more than 623 ​
____ [38]
There are many ways, but here is one:

x = 100

Since ‘x’ is 100 and we want 100 more, we just need to add ‘x’ to 623

Answer: x + 623 (Make sure you define your ‘x’ value)

(9+8)+6/3-7×2 how to slove
klemol [59]

Answer:

Step-by-step explanation:

There is a specific order to do these kind of problems..

first, we do everything in parenthesis...

(9 + 8) + 6/3 - 7 * 2

17 + 6/3 - 7 * 2

now, starting from the LEFT side, do all multiplication and division in the order it comes

17 + 2 - 14

now, starting from the LEFT side, do all addition and subtraction in the order it comes

19 - 14 = 4

so ur answer is 4

Learn this...order of operations....this is the order u do these problems in..

PEMDAS

P = parenthesis

E = exponents

M = multiplication

D = division

A = addition

S = subtraction

keep in mind, multiplication/division are done from left to right....u do not have to do multiplication before u do division....it just depends on which comes first when starting from the left side.....that also applies to addition/subtraction
