2x+3-x=7 what is the answer to this by using solving multistep equations using combining like terms

Hey there! I'm happy to help!

Like terms are numbers with the same variable and same power. 5 and 7 are like terms because they have no variable. 6x and 6y are not because they have different variables. 7x² and 6y² are also not like terms because they have different variables. 7x and 5x are like terms, and 5y³ and 9y³ are like terms.

We see that 2x and -x have the same variables. We can then combine them.

2x-x=x

Now we have x+3=7.

We subtract 3 from both sides, giving us x=4.

Have a wonderful day! :D

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
