Solve for x 5x+5x+3=4(2x+1)-2

1 answer:

6 0

We need to add like terms and distribute before we try to isolate X.
10x+3=8x+4-2
10x+3=8x+2

Now let's isolate x. We should start with subtracting 8x from both sides.
2x+3=2
Now, let's subtract 3 from both sides.
2x=-1
Now divide each side by 2.
X=-0.5
We now know x is -0.5, so let's check.
5(-0.5)+5(-0.5)+3=4[2(-0.5)+1]-2
-2.5-2.5+3=4(0)-2
-5+3=0-2
-2=-2

So, X= -0.5

Ax +by=c solve for y

hichkok12 [17]

Answer:

y = c/b - (A x)/b

Step-by-step explanation:

Solve for y:

A x + b y = c

Hint: | Isolate terms with y to the left hand side.

Subtract A x from both sides:

b y = c - A x

Hint: | Solve for y.

Divide both sides by b:

Answer: y = c/b - (A x)/b
