Question

Simplify these terms

-10(1+6x)

-2(8x-7)

(7x-3)6

-3(-8x+8)

Answer 1

Multiply the -10 by all the numbers in the bracket.... Just expand the bracket and simplify.

Remember -x- = positive and -x+=negative

1) -10-60x

-10-60x=0

-60x=10

x=-10/60

x=1/6

2) -16x+14

-16x+14=0

-16x=14

x=-14/-16

x=7/8

3) 42x-18

42x-18=042x=18

x=18/42

x=3/7

4)24x-24

24x-24=0

24x=24

x=24/24

x=1

Answer 2

In order : Bracket power division multiplication addition subtraction
Means BODMAS
1. -10-60x
2. -16x+14
3. 42x-18
4. 24x-24
Why + and - are different
Remember this
- ( multiplies to) - = +
- (multiplies to ) + = - ( and vice versa)
