Multiply the top equation by -3 and the bottom equation by 2.
I assume that you mean that you are given a differential equation dy/dx and want to solve it. If that is the case, then you would multiply by dx on both sides and then integrate both the left and right sides of the equation.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
I=Prt is a multiplication problem. All you need is the Principle, rate, and time. Then you multiply then together.
The multiplicative property of equality. Multiply each side by -1/3.
a proportion is an equation. a / b = c / d cross multiply: ad = bc then solve
To find the answer to this you will need to create a proportion with one variable. Then cross multiply and finally solve a one-step equation. Set it up like this:49/100 = 16/NThen cross multiply:16 x 100 = 49 x N1600 = 49NThen solve the one-step equation to find your answer.Hope this helps.
cross multiply you lazy bumAnother AnswerSet up the equation and solve: x/1.2 = -7 (next divide both sides of the equation by 1.2 to solve for x)x = -5.8333
To solve a proportion, you cross multiply. For example, if this was the proportion: 2/4 = 3/x, you would multiply 2 with x and 4 with 3. The products will be used in your next equation. In this case, your next equation is 2x = 12. Now you want to isolate x, so divide by two for both sides. Your answer will be x = 6.
set up a proportion. cross multiply. solve
cross multiply to solve: 100 x 4200 = 87 Y solve for Y by doing 420,000 divided by 87, which equals 4828 (rounded off)
You can cross-multiply or go on Google for more help...
Cross multiply then solve for the variable.
multiply the whole equation by the number in the denominator
There is no need. The first equation can be rearranged to a simple equation in just y. Multiply it by 0.2 to solve for y. Substitute the value of y in the second equation and rearrange to get a simple equation in x. Multiply by (1/6) to find x.
determinents - you cross multiply and find the difference.
