Simplify 3 (x+2) + 4 (x-5)

7x - 14

Step-by-step explanation:

3 (x+2) + 4 (x-5)

Distribute

3x+6 + 4x - 20

Combine like terms

7x - 14

1.

multiply 3 with the variable and number in the bracket

so (3x+6)

then multiply 4 with the variable and number in the bracket

so (4x-20)

New equation:

(3x+6) + (4x-20)

Combine like terms and add them

so 4x+3x and 6-20

remember the rules of negative with positives

ur new equation is

7x-14

now you can divide to find x

divide 7 on both sides

so

x=-2
