Step-by-step explanation:
➱ What is an equation?
Equation is a mathematical account that involves letters that are called unknowns the most used are X and Y. And it has many degrees we will see below the second degree.
➱ How to do a normal equation resolution:
➤ To solve equations we must separate the numbers with unknowns that are in the equation for the left side of the equals.
➤ And we must pass the numbers without unknowns to the right side of the equals.
➤ When the numbers are on the wrong side of the equals, we change the sign every time we change sides.
Rules:
➢ Numbers with unknowns = left side of the equals.
➢ Numbers without unknowns = right side of the equals.
➢ Changing sides = change the signal too.
========================
Answer:
y= -5+32
3x-5(-5+32) =22
3x-25+160=22
3x= 22+25-160
3x= 47-160
3x= -113
x= [tex]\frac{-113}{3}[/tex]
X= -37,6666666667
