Answer:
33 inches
Step-by-step explanation:
x=length of board
x+2x=99
3x=99
x=33
Well think, does 7 go into 72?
The correct answer is:
A. 14x+6y= 10
-14X-35y=77
Further explanation:
One method of solving system of linear equations in two variables is elimination method. In this method, the co-efficient of one variable have to be equated so that variable can be removed to get the value of other variable.
Given equations are:
As we have to eliminate x, then the co-efficient of x will be equated. For this purpose both equations will be multiplied with some constant.
So,
multiplying equation one with 2
Multiplying equation 2 by -7
So,
The correct answer is:
A. 14x+6y= 10
-14X-35y=77
