Question

(3x+4)–(2x+9)=15

Help meeeeeeeeeeeee.

Answer 1

x = 20

Explanation:

We are given the equation ( 3x + 4 ) – ( 2x + 9 ) = 15;

( 3x + 4 ) - ( 2x + 9 ) = 15 ⇒ Take ( ) out, through distribution of - 1,

3x + 4 - 2x - 9 = 15 ⇒ Subtract 4 from either side,

3x - 2x - 9 = 11 ⇒ Combine like terms,

x - 9 = 11 ⇒ Add 9 on either side,

Solution; x = 20

Answer 2

x=30

Explanation:

you distribute the negative to 2x and 19

3x+4-2x-19=15

then you combine like terms

x-15=15

you add 15 to both sides

x=30
