Answer 5

@SolomonZelman tell me if this is rite?



Solution for 8x+9=7x+6 equation:


Simplifying
8x + 9 = 7x + 6

Reorder the terms:
9 + 8x = 7x + 6

Reorder the terms:
9 + 8x = 6 + 7x

Solving
9 + 8x = 6 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.
9 + 8x + -7x = 6 + 7x + -7x

Combine like terms: 8x + -7x = 1x
9 + 1x = 6 + 7x + -7x

Combine like terms: 7x + -7x = 0
9 + 1x = 6 + 0
9 + 1x = 6

Add '-9' to each side of the equation.
9 + -9 + 1x = 6 + -9

Combine like terms: 9 + -9 = 0
0 + 1x = 6 + -9
1x = 6 + -9

Combine like terms: 6 + -9 = -3
1x = -3

Divide each side by '1'.
x = -3

Simplifying
x = -3

Answer 6

Yes, it's right, but you could have done this much simpler.

Answer 7

I still do not understand the question....are you setting them equal to each other and solving for x or what ?

Answer 8

@how?

Answer 9

are you trying to set them equal to each other and solve for x ??

Answer 10

ignore the @

Answer 11

yes @texaschic101

Answer 12

8x + 9 = 7x + 6 -- subtract 9 from both sides
8x + 9 - 9 = 7x + 6 - 9 -- combine like terms
8x = 7x - 3 -- subtract 7x from both sides
8x - 7x = 7x - 7x - 3 -- combine like terms
x = -3

check..
8x + 9 = 7x + 6
8(-3) + 9 = 7(-3) + 6
-24 + 9 = -21 + 6
-15 = -15 (correct)

Answer 13

Yes @texaschic101
