Answer:

7 1/2

Step-by-step explanation:

Change each into improper fractions

3 1/3 = (9 + 1)/3 = 10/3

2 1/4 = (8 + 1)/4 = 9/4

Next, multiply across

(10/3) x (9/4) = 90/12

Simplify.

90/12 = 15/2, or 7 1/2

7 1/2 is your answer

2x-5y=9<br> 3x+4y=2<br> solve the simultaneous equations
wariber [46]

\huge\boxed{x=2;\ y=-1}

\left\{{{2x-5y=9}\atop{3x+4y=2}}\right

First, we will solve the second equation for x. Subtract 4y from both sides of the second equation.

3x=2-4y

Divide both sides of the second equation by 3.

x=\frac{2}{3}-\frac{4}{3}y

\left\{{{2x-5y=9}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right

Substitute the value of x from the second equation into the first.

\left\{{{2(\frac{2}{3}-\frac{4}{3}y)-5y=9}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right

2(\frac{2}{3}-\frac{4}{3}y)-5y=9

We will solve the first equation for y.

Distribute the 2 to the (\frac{2}{3}-\frac{4}{3}y).

\frac{4}{3}-\frac{8}{3}y-5y=9

Combine the like terms.

\frac{4}{3}-\frac{23}{3}y=9

Add \frac{4}{3} on both sides.

-\frac{23}{3}y=9-\frac{4}{3}

-\frac{23}{3}y=\frac{23}{3}

Divide both sides by \frac{23}{3}.

-y=1

Multiply both sides by -1.

y=\boxed{-1}

Substitute the value of y into the second equation.

\left\{{{y=-1}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right

x=\frac{2}{3}-\frac{4}{3}*-1

Multiply.

x=\frac{2}{3}+\frac{4}{3}

Add.

x=\frac{6}{3}

x=\boxed{2}
