What is the value of x?

1. 6 (-3 - x) - 2x = 14

x=

2. 2/7x + 6 + 17x = 18

x=

1) expand the brackets

6 (-3 - x) - 2x = 14

-18 - 6x - 2x = 14

simplify

-18 - 8x = 14

then add 18 to both sides to get the x's on there own

-8x = 32

then divide by - 8

x = 32/-8

x = - 4

2) multiply everything by 7x

2 + (6 x 7x) + (17x * 7x) = 18 x 7x

2 + 42x + 119x^2 = 126x

put everything on one side

119x^2 - 84x + 2 = 0

then use quadratic equation to solve

x = 0.024671849 or 0.6812105039
