Answer:

-2/3 or - 0.667

Step-by-step explanation:

2 x 2 + 3x = 2

4 + 3x = 2

collect like terms so that components involving x can stand alone

3x = 2 - 4

3x = -2

divide both sides by the coefficient of x which is 3

3x/3 = -2/3

x = -2/3 or -0.667

Simplify the answer -12 ÷ 3 × (-8 + (-4)² - 6) + 2 I need the steps for the equation on how to solve it.
aleksley [76]

Answer:

-6

Step-by-step explanation:

We use PEMDAS to solve this,

so P stands for parentheses, so that's where we start.

We first, square the innermost parentheses with the exponent which is the E in PEMDAS, then then the outer parentheses

-12/3*(-8+16-6)+2

-12/3*(2)+2

Now we divide as in Division in PEMDAS.

-4*2+2

Now we multiply as in Multiplication in PEMDAS.

-8+2

Now we add as in A for Addition

-6

In PEMDAS, Multiplication doesn't always come before division, and same for addition and subtraction.
