3(x-4)=5(x+2)
Answer:
x = -11
Step-by-step explanation:
1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis
3x-12 = 5x + 10
2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)
2x = -22
3. Divide both sides by 2
x = -11
please give me brainliest if this helped
Answer:
x=−11
Step-by-step explanation:
3(x-4)=5(x+2)
Simplify both sides of the equation:
3(x−4)=5(x+2)
(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)
3x−12=5x+10
Subtract 5x from both sides
−2x−12=10
add 12 to both sides
−2x=22
Divide by -2 both sides
x=−11
Hope this helps.

Which of the following is a correct interpretation of the expression 2 - (-5)
A The number that is 5 to the left of 2 on the number line
B The number that is 5 to the right of 2 on the number line
C The number that is 2 to the left of -5 on the number line
D The number that is 2 to the right of -5 on the number line
Answer:
B
Step-by-step explanation:
when rewriting it, it would be 2+5 because subtracting a negative number is the same as adding.
so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)
