Will mark brainliest 4x+66 = 7x+15 what is x?

4x + 66 = 7x + 15     subtract 66 from both sides

4x = 7x - 51     subtract 7x from both sides

-3x = -51    divide both sides by (-3)

x = 17

x=17 and 17=x. *The answer should 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

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

subtract by 66 both sides of an equation.

4x+66-66=7x+15-66

simplify by equation.

4x=7x-51

subtract 7x both sides of an equation.

4x-7x=7x-51-7x

simplify.

-3x=-51

divide by -3 both sides of an equation.

-3x/-3=-51/-3

simplify.

51/3=17

51/17=3

17*3=51

3*17=51

It changes negative to positive.

x=17

Hope this helps!

Thanks!

Have a great day!
