-4(3x+10)-2=54

x=?

3 answers

To solve this equation, we will first distribute the -4 to the terms inside the parentheses:

-12x - 40 - 2 = 54

Next, we combine like terms:

-12x - 42 = 54

To isolate the variable, we will add 42 to both sides:

-12x = 54 + 42

-12x = 96

Finally, we divide both sides by -12 to solve for x:

x = 96 / -12

x = -8

Therefore, x = -8.
20x-5(6x+15)=-45
x=?
To solve this equation, we will first distribute the -5 to the terms inside the parentheses:

20x - 5(6x+15) = -45

20x - 30x - 75 = -45

Next, we combine like terms:

-10x - 75 = -45

To isolate the variable, we will add 75 to both sides:

-10x = -45 + 75

-10x = 30

Finally, we divide both sides by -10 to solve for x:

x = 30 / -10

x = -3

Therefore, x = -3.
