Let x and x+2 be there integers. then
3x=5(x+2)-116
3x=5x+10-116
2x=106
x=53
numbers are 53 and 55
Negative 34 means (-34)
times means to multiply, then

To do it without a calculator we will make -34
-30 + -4, then multiply -30 by 1567 and multiply -4 by 1567 then add the two answers


Then add the answers

The answer is -53278
X-30+x-30+x=180
3x-60=180
3x=240
X=80
We first find A2, for which we multiply A with itself. We perform matrix multiplication in which we multiply rows of first matrix with columns of second matrix element by element and add.
