Solve using substitution: y + 2x = -1 and y - 3x = 16

Alright i'm just going to assume your doing both of them one at a time.

y + 2x = - 1: So Alright Graph using the slope and y-intercept

Slope: - 2

Y-intercept: - 1

And the other

- 3x = 16: same as well So the Answer to this is Except solve for x by simplifying both sides of the equation, then isolating the variable

Exact form: x = - 16/3

Decimal form: x = - 5.3 Well Hope this helps :)

Step-by-step explanation:

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

3.how is solving radical equations different than solving linear equations?
