I'll do 1 and 8, and you should then be able to do 2 and 9!

For 1, we can multiply these separately - 3*4*9=108 and 5+7+2=13 (exponent multiplication is adding them!), so we have 108b^13

For 8, we can again add the exponents up to get (5/7)^8

Solve 3x+2y=4 4x+3y=7 algebraically

Leona [35]

Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
$\left \{ {{-9x-6y=-12} \atop {8x+6y=14}} \right.$

Step 2. Add both equations together. You'll get:
$-x=2$ , which gives x = -2

Step 3. Replace x = -2 in the first equation and calculate y.
$3(-2)+2y=4\\
y=\frac{4+6}{2}=5$

The solution is: x=-2, y=5

-3=x/-9 please tell me how to solve this I’m way behind and trying to learn thank you :)

snow_tiger [21]

-3 = x/-9

To make this easier, I'll put it in normal numbers

(-3 = x/-9) -1

3 = x/9

Multiply both sides by nine to take out the division.

27 = x

Hope that this helped!
