(3x+4y= 10)
(2x+3y=7)
Using elimination

The solution of the equations are (2,1)

Explanation:

The given equations are

----------(1) and

---------(2)

We need to determine the solution of the equation using elimination method.

Multiplying the equation by 2, we get,

-------(3)

Multiplying the equation by -3, we get,

-------(4)

Adding the equation (3) and (4), we have,

Thus, the value of y is 1

Substituting the value of y in equation (1), we have,

Thus, the value of x is 2.

Hence, the solution of the equation is (2,1)

step-by-step explanation:

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)
