Answer:
1
Step-by-step explanation:
9 - 4 x 2
4 x 2 = 8
9 - 8 = 1
Answer:
2x+y=15x+y=10
Consider the first equation. Subtract 15x from both sides.
2x+y−15x=y
Combine 2x and −15x to get −13x.
−13x+y=y
Subtract y from both sides.
−13x+y−y=0
Combine y and −y to get 0.
−13x=0
Divide both sides by −13. Zero divided by any non-zero number gives zero.
x=0
Consider the second equation. Insert the known values of variables into the equation.
15×0+y=10
Multiply 15 and 0 to get 0.
0+y=10
Anything plus zero gives itself.
First of all, I suppose that you are dividing, /.
Since, you don't have any other symbols here, i.e. + -*.
you work from left to right
