Answer 3

Solution for 9x+7=3x+43 equation:

Simplifying
9x + 7 = 3x + 43

Reorder the terms:
7 + 9x = 3x + 43

Reorder the terms:
7 + 9x = 43 + 3x

Solving
7 + 9x = 43 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.
7 + 9x + -3x = 43 + 3x + -3x

Combine like terms: 9x + -3x = 6x
7 + 6x = 43 + 3x + -3x

Combine like terms: 3x + -3x = 0
7 + 6x = 43 + 0
7 + 6x = 43

Add '-7' to each side of the equation.
7 + -7 + 6x = 43 + -7

Combine like terms: 7 + -7 = 0
0 + 6x = 43 + -7
6x = 43 + -7

Combine like terms: 43 + -7 = 36
6x = 36

Divide each side by '6'.
x = 6

Simplifying
x = 6

Answer 4

thx

Answer 5

Am I missing something? Why are you solving @jordanloveangel
9x+7=3x+43

Answer 6

ur method is wrong @jordanloveangel

Answer 7

but its the right answer

Answer 8

Ok so the process you want to use for this is elimination. Multiply the top equation by 3.
3(3x+5y=43) = 9x+15y=129
Now both equations have a 9x
9x+15y=129
9x+7y=83
Subtract the second equation from the first
8y=46
Divide both sides by 8.
y= 5.75
To find x substitute y in
x= 4.75

Answer 9

I agree with @mathmath333

Answer 10

wait wait

Answer 11

Solution for 3x+5y=43 equation:

Simplifying
3x + 5y = 43

Solving
3x + 5y = 43

Solving for variable 'x'.

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

Add '-5y' to each side of the equation.
3x + 5y + -5y = 43 + -5y

Combine like terms: 5y + -5y = 0
3x + 0 = 43 + -5y
3x = 43 + -5y

Divide each side by '3'.
x = 14.33333333 + -1.666666667y

Simplifying
x = 14.33333333 + -1.666666667y

Answer 12

9x + 7 \(\neq \) 3x + 43
\(43\neq 83\)

Answer 13

Solution for 9x+7y=83 equation:

Simplifying
9x + 7y = 83

Solving
9x + 7y = 83

Solving for variable 'x'.

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

Add '-7y' to each side of the equation.
9x + 7y + -7y = 83 + -7y

Combine like terms: 7y + -7y = 0
9x + 0 = 83 + -7y
9x = 83 + -7y

Divide each side by '9'.
x = 9.222222222 + -0.7777777778y

Simplifying
x = 9.222222222 + -0.7777777778y
