Question

7x-3x-8=24 what is the value of x

Answer 1

Answer: x=8 and 8=x. *The answer must be have positive sign.*

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!
