Step-by-step explanation:
Given equations
2x + 5y = 6 .......i)
2x = 10 - 3y...... II)
Putting 2x = 10 - 3y in equation i
10 - 3y + 5y = 6
2y = 6 - 10
2y = - 4
y = - 4 / 2
y = - 2
Now putting y = - 2 in equation ii
2x = 10 - 3 * ( - 2)
2x = 10 + 6
2x = 16
x = 16 / 2
x = 8
So x = 8 and y = - 2
Hope it will help :)❤
Answer:
3
Step-by-step explanation:
Input: -3
output: 2
"Some possible rules" are equations using variables to make the input (x) equal to the output (y).
1) x + 5 = y
2) -2x - 4 = y
3) -x - 1 = y
Answer:
D; 2 * 3; -4
Step-by-step explanation:
The dimension of the matrix refers to the number of elements in a row multiplied by the number of elements is a column
In a row, we have 2 elements, in a column , we have 3 elements
So the matrix is of 2 * 3 dimension
a21, refers to the element in the matrix that is in the row 2 column 1 and that is -4
