Answer:
Step-by-step explanation:
First rearrange all equations into this format:
that will result in:
then we'll multiply an equation with a number such that we have same numbers on both equations (with only different signs). So we can add them
Here you can see that we've multiplied the first equation with (-3) so that we have -9x on one equation and 9x on the other. Now when we add the two equations the 9x and -9x terms will cancel out (or eliminate)
now that we've found the value of y
we'll use this value in any of the two equations to get the value of x.
let's put y in the first equation:
Answer:
- 16.7° C
Step-by-step explanation:
Decreasing by - 1.5° C means subtracting this from - 15.2° C , that is
- 15.2° C - 1.5° C = - 16.7° C
