1.) First of all, start
by adding 13 to
both sides. The 13
will
cancel out the -13. The
equation is now 4x=
48
4 4 2.) Divide both sides by 4 and the answer is 12.

Equation#2
1) With slope=3 through (2,9) slope: Y-9=7 X-2 Y-9=3(x-2) |
The point-slope form is being used. First start by subtracting 9by Y and 2 by X. Now take points (2,9) and form an equation. The equation comes out to be Y-9=3(which is the slope). Next subtract the Y-9 with the X-2. The answer is Y-9=3(X-2). |
| Equation#3
1) A=(b1+b2)H 2 2) 2a=(b1+b2)H H H 3) 2b=b1+b2 a 4) 2a-b2=b1 H |
1.) First, start by mulityplying
the 2 by everything.
Next divide the H by
both sides. The equation is now 2b=b1+b2.
a 2.)Next divide the H by everything. The H cancels out. 3.) The equation is now 2a-b2=b1. H |
