If you are solving for X, follow this below.

Flip the equation.

2x−7=−3y

Add seven to both sides.

2x−7+7=−3y+7

2x=−3y+7

Divide both sides by 2.

x= -3/2y + 7/2

Therefore, x= -3/2y + 7/2 is your final answer.

IF your solving for Y, follow below.

−3y=2x−7

Divide both sides by three.

-3y/-3 = 2x-7/-3

Therefore, for Y you have y = -2/3x + 7/3 simplified.

Answer:

X=-3y/2 + 7/2

y=-2x/3+ 7/3

Step-by-step explanation:

Isolate the variables by dividing each side by factors that don't contain the variable. (solving for x)

Divide each term by −3 and simplify. (solving for y)

You didn't say which one you wanted solve but hope this helps.

What is the solution for the equation 3x + 0.3 = 3.3.

hoa [83]

Answer:

3x+0.3=3.3.

\ /

We move all terms to the left:

3x+0.3-(3.3.)=0

We add all the numbers together, and all the variables

3x+0.3-0=0

We add all the numbers together, and all the variables

3x+0.3=0

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

3x=-0.3

x=-0.3/3

Which value is equivalent to 48 ÷ ((2 + 6) × 2) − 1? A) -12 B) 2 C) 3 1 5 D) 3

timama [110]

Answer:

B) 2

Step-by-step explanation:

Given expression,

48 ÷ ((2 + 6) × 2) − 1

In simplification we follows the following order,

B = Bracket

O = Of

D = Division

M = Multiplication

A = Addition,

S = Subtraction,

Thus, steps of solving the given expression by following BODMAS are as follow,

$\frac{48}{(2 + 6) \times 2}-1$

$=\frac{48}{8\times 2}-1$

$=\frac{48}{16}-1$

$=3-1$

$=2$

Hence, OPTION B is correct.
