7x-3x-8=24 what is the value of x
2 answers:
<u><em>Answer: x=8 and 8=x. *The answer must be have positive sign.* </em></u>
Step-by-step explanation:
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
distributive property: a(b+c)=ab+ac
add the numbers.
7x-3x=4x
4x-8=24
add by 8 both sides of an equation.
4x-8+8=24+8
simplify by equation.
24+8=32
4x=32
divide by 4 both sides of an equation.
4x/4=32/4
simplify by equation.
32/4=8
32/8=4
8*4=32
4*8=32
It change negative to positive.
x=8 and 8=x
Hope this helps!
Thanks!
Have a great day!
Answer:
x = 8
Step-by-step explanation:
7x - 3x - 8 = 24
Simplify the terms in x:-
4x - 8 = 24
Add 8 to both sides:-
4x = 32
4x / 4 = 32/4
x = 8 answer
