Find x helpppppppppppp

lidiya [134]

$|2x - 1| = | - x - 2|$

Thus ;

$2x - 1 = - x - 2$

Add both sides x

$2x + x - 1 = - x + x - 2$

$3x - 1 = - 2$

Add both sides 1

$3x - 1 + 1 = - 2 + 1$

$3x = - 1$

Divide both sides by 3

$\frac{3x}{3} = \frac{ - 1}{3} \\$

$x = - \frac{1}{3} \\$

$2x - 1 = - ( - x - 2)$

$2x - 1 = x + 2$

Subtract both sides x

$2x - x - 1 = x - x + 2$

$x - 1 = 2$

Add both sides 1

$x - 1 + 1 = 2 + 1$

$x = 3$

There u go ...

-(7-9)z-6z=8(-6+2) solve for z

Sergeeva-Olga [200]

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

C. 3x + 7 because you can factor out the other 3.
a. 16+4x=4(4+X)
b. 25x+30y=5(5x+6y)
d. 40x-30y = 5(8x-6y)

if you want to buy a shirt that cost 18.99 but you have 20% off coupon and the tax is 7%. how much does the shirt cost

dusya [7]

20% off means you pay 80% of the price so you multiply by 0.8, and 7% tax means you multiply by 1.07

Resulting cost = 18.99*0.8*1.07 = 16.26

Hope this helps let me know if im wrong!
