−16x²
Step-by-step explanation:
Simplifying!
The value of d which will.make this system have the same solution is; d = 21/(3x -1)
First, we must make y, the subject of the formula in each case as follows;
- y = (3x -1)/7. and
- y = 3/d.
In essence, by equating y to y in both equations; we have;
By Cross-product; we have;
