4(1 - x) + 2 x = -3(x + 1)

please help me :(

x = 7

Step-by-step explanation:

4 (1 - x) + 2x = -3 (x + 1)

4 - 4x + 2x = -3x -3

4 - 2x = -3x - 3

  + 3x     + 3x

4 - x = -3

- 4       - 4

-x = -7

x = 7

-14 is the answer

hope this : ))

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
