x=4

Step-by-step explanation:

4(-6+5x)=24+8x

open the bracket

-24+20x=24+8x

collect like terms

20x-8x=24+24

12x=48

divide both sides by 12

12x/12 = 48/12

x= 4

-7+7n=2(-7+7n)

open the brackets

-7+7n=-14+14n

collect like terms

14n-7n=-14+7

7n=-7

divide through by 7

n=-1

Bond [772]

Answer:

x = 21

Step-by-step explanation:

Diagonal angles are equal to eachother, so 143 = 6x +17

143 = 6x + 17

Subtract 17 from both sides

126 = 6x

Divide by 6

21 = x

To check put x as 21

143 = 6(21) + 17

Mutiply 6 by 21

143 = 126 + 17

add 17

143 = 143
