3x -2=13 what is x ...........

Tom [10]

Methods:

$3x-2=13$

=> $3x-2+2=13+2$

=> $3x+0=15$

=> $3x=15$

=> $\frac{3}{3}x= \frac{15}{3}$

=> $x = \frac{5}{1}$ or $5$

or, (do side changing)

$3x-2=13$

=> $3x=13+2$

=> $3x=15$

=> $x= \frac{15}{3}$

=> $x= \frac{5}{1}$ or $5$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Step-by-step explanation:

Step 1: Define

2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y

x = -1

y = 2

Step 2: Evaluate

Substitute: 2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
Exponents: 2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
Multiply: -16 - 6 + 24 + 2 - (-2) + 4
Simplify: -16 - 6 + 24 + 2 + 2 + 4
Subtract: -22 + 24 + 2 + 2 + 4
Add: 2 + 2 + 2 + 4
Add: 4 + 2 + 4
Add: 6 + 4
Add: 10
