Write whether the following pair of linear
equations is consistent or not: x+y=14 & X-y=4

The linear equation is consistent

Step-by-step explanation:

X+y=14(1)

X-y=4(2)

Add (1) and (2)

2x=28

Divide both sides by 2

x=14

Substitute the value for x into (1)

14+y=14

Substrate 14 from both sides

y=0

So the linear equation is consistent

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
