What’s the right process used to achieve steps 1-4

x=1.875

Step 1: you need to multiply the brackets.

-2(5x+8) = -10x-16

-10x-16=14+6x

Step 2: you want to put the x on one side, so take away 6 x from both sides

-10x-6x=-16x, 6x-6x=0

-16x-16=14

Step 3: add 16 to both sides so the whole numbers are on one side

-16+16=0, 14+16=30

-16x=30

Step 4: finally, divide the whole by the number of x, so 16

x=1.875

If you need to round it to a significant figure:

1 Sf: x=1.9

2Sf: x=1.78

3 Sf: the final answer only has three figures after the decimal.

Hope this helps, have a wonderful day!

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
