Ok let's do this*pops knuckles*
let's add the first side

order of operations demands that we do multiplication first(P.E.M.D.A.S)
so

now we can add the 1 from

into our six

now we substract

now we have

now we focus on the
other side

since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.

now we have

(the three is from the original equation)
now we plug in our final numbers

or

I hope this helps
Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
Answer:
x = 11
Step-by-step explanation:
• All interior angles in a triangle add up to 180.
• The square in the triangle represents 90°
90 + 45 + 1 + 4x = 180
136 + 4x = 180
4x = 180 - 136
4x = 44
x = 11
