Here we MUST follow Order of Operations rules.
Must start out by doing the work inside the parentheses: (8+7) = 15
Next, multiply this result by 3: 3(15)=45 (answer)

You will have to work out the given versions of this problem until you find one that is also equal to 45.

How many solutions does the system of equations have? 2x + 3y = 6 y=2/3x-1 A. 0 B. 1 C. 2 D. infinite

Dvinal [7]

Answer:

The answer is B) 1.

Step-by-step explanation:

Combine the equations like this:

$2x+3y=\frac{2}{3}x-1$

Then subtract $3y$ from all sides.

$2x+3y-3y=\frac{2}{3}x-1-3y$

Simplify the equation.

$2x=\frac{2}{3}x-1-3y$

Then subtract $\frac{2}{3}x$ from all sides.

$2x-\frac{2}{3}x=\frac{2}{3}x-1-3y-\frac{2}{3}x$

Simplify again.

$\frac{4}{3}x=-1-3y$

Multiply all sides by $3$ .

$3\times \frac{4}{3}x=-3\times 1-3 \times 3y$

Simplify again.

$4x=-3-9y$

Divide all sides by $4$

$\frac{4x}{4}=- \frac{3}{4}- \frac{9y}{4}$

Simplify again.

$x= \mathbf{\frac{-3-9y}{4}}$
