-7x + 6 =27
subtract 6 from both sides
-7x =21
divide both sides by -7
x= -3

Answer:
9 ÷ 15x
Step-by-step explanation:
( 52 - 43 ) /3x ( 2 + 3)
PEMDAS
Parenthesis, Exponents, Multiplication, Divison, Addition, Subtraction
Do the parenthesis first.....
52 - 43 = 9
9 ÷ 3x ( 2 + 3)
Parenthesis ( do the distributive property...multiply 3x by whatever is inside the parenthesis)
9 ÷ 3x × 2 + 3x × 3
9 ÷ 6x + 9x
Combine like terms (both x's)
9 ÷ 15x
You can't do anymore, since it is just an expression, and not an equation
Hope this helped!
Have a supercalifragilisticexpialidocious day!
