(-2x+10)-(-8x-1)

Question

Could you show ma how to do it please?

Answer 1

-2x + 10 - (-8x - 1) = 0

PEMDAS is the order of operations: do what's in parentheses first, then exponents, multiplication, division, addition and subtraction, in that order

there's nothing you can do within the parentheses. It's apples & oranges, a variable term and a constant term. All you can do is leave them as they are: -8x-1. There are no exponents, so next step is multiplication. Multiply an implicit -1 times (-8x-1) that give (-1)(-8x) -(-1)(1) = 8x+1

-2x +10 +8x+1 = 0

combine like terms put the x terms together, and separately put the constant terms together

-2x + 8x + 10+1= 0

(8-2)x = -11

6x =-11

divide both sides by 6

x = -11/6

x = 19/6
