Answer:

-(7x-8)=9x-4

We move all terms to the left:

-(7x-8)-(9x-4)=0

We get rid of parentheses

-7x-9x+8+4=0

We add all the numbers together, and all the variables

-16x+12=0

We move all terms containing x to the left, all other terms to the right

-16x=-12

x=-12/-16

x=3/4

uranmaximum [27]

Answer:

[0, 3, -6]

Step-by-step explanation:

{4x + y = 3

{x + y - z = 9 ←

{2x + 2y + z = 0 ←

−¾[4x + y = 3]

{−3x - ¾y = −2¼ >> New Equation

{3x + 3y = 9

_________

2¼y = 6¾

___ ___

2¼ 2¼

y = 3 [Plug this back into all three equations to get the z-value of −6, and the x-value of 0]; 0 = x; -6 = z
