3x + x = 31 + 5;

4x = 36;

x = 36/4;

x = 18

-(2x - 5) = 4; -2x + 5 = 4; -2x = 4 - 5; -2x = -1; x = 1/2

- - -

(2x - 5) = 4; 2x = 4 + 5; 2x = 9; x = 9/2,

x = 1/2 or x = 9/2

Simplify: 2(4 + 6x) = 8 + 12x;

Combine like terms: 3x + 8 + 12x = 113; 15x + 8 = 113;

Add -8 on both sides: 15x + 8 - 8 = 113 - 8; 15x = 105;

Divide both sides by 15: 15x/15 = 105/15; x = 7

Solution is x = 7

To check, substitute x to 7:

15(7) + 8 = 113;

105 + 8 = 113;

113 = 113

= 2x^2 - 3x^3 - 5x^2 + 9x^3

= (- 3x^3 + 9x^3) + (2x^2 - 5x^2)

= 6x^3 - 3x^2

= 4(2x - 3)/x^2(2x - 3)

= 4/x^2

To solve for y in the equation 2x + y = 5, subtract 2 from both sides of the equation. FALSE.

2x should be subtracted to solve for y.

2x should be subtracted to solve for y.

-(2x + 4) = 18

-2x - 4 = 18

-2x = 18 + 4 = 22

x = 22/-2 = -11

-2x - 4 = 18

-2x = 18 + 4 = 22

x = 22/-2 = -11

9x^2 and 5x are like terms. FALSE.

The exponent is different, they are not like terms.
