(3x — 3), (4y+4)°/60° Solve for y.​
ololo11 [35]
(4y+4)+(3x-3)=180 (cause they are supplementary)

4y+3x=179
4y=179-3x
so
y= 179/4 - 3/4x (write these as a fraction; the x goes to the whole fraction)

u cant get a more exact result with 2 unknowns:)

THE SOLUTIONS OF A SYSTEM OF EQUATIONS

A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The situation gets much more complex as the number of unknowns increases, and larger systems are commonly attacked with the aid of a computer.

A system of two linear equations in two unknowns might look like

This is the standard form for writing equations when they are part of a system of equations: the variables go in order on the left side and the constant term is on the right. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.

describe a real-world situation that can be modeled by the equation y=1/20x. Be sure to describe what each variable represents.
MissTica
Y = 1/20x

In this equation, y is equal to one twentieth times x. Using PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction) from left to right, we would first divide 1 by 20 and then multiply it by x. An example of a real world problem is this:

Georgia is throwing a party for her friends. She has a large cake to split among all of the party guests. She has cut the cake into 20 slices for each of the friends who show up. She wants to know how much cake she will give in total to all of her friends.

 In this equation, y is equal to the total amount of cake that will be eaten by Georgia's friends at the party. Because the cake is sliced into 20 pieces, each friend will receive 1/20 of the cake. X is equal to the number of friends who show up to the party.
