8x+21=3 need the answer please

GarryVolchara [31]

Answer:

$x=-\frac{9}{4}$

Step-by-step explanation:

<u>Step 1: Subtract 21 from both sides</u>

$8x + 21 = 3$

$8x + 21 - 21 = 3 - 21$

$8x = -18$

<u>Step 2: Divide 8 from both sides</u>

$8x = -18$

$\frac{8x}{8}=-\frac{18}{8}$

$x=-\frac{9}{4}$

Answer: $x=-\frac{9}{4}$

Solve in systems by substitution y=2x+1 and 2x-y=3

nika2105 [10]

Answer: No Solution

Step-by-step explanation:

y=2x+1 and 2x-y=3

Substitute y=2x+1 into 2x-y=3

So you will have: 2x-2x+1=3

Then,

2x-2x=0

0+1=3

1=3

1 doesn't equal 3 so there is no solution.
