solve x+y=5, 2x+2y=10

Solve 3x - 4y = 20 and x + 2y = 5.

If 3x+5y=15 and x-2y=10 , what is the value of 2x+7y ?

Use method of cross-multiplications to solve: 2x + y = 8 and 3x- 2y = 5

Solve x + y = 10 and x - y = 4.

Solve : 2x+ 7y =11 5x + (35)/(2) y = 25

Solve : 3x+ 2y = 14 - x+ 4y = 7

Solve 2x + 5y ge 10

Solve the following system of equations graphically: x-2y=5;\ \ \ 2x+3y=10

Solve 11(x - 5) + 10(y - 2) + 54 = 0 7(2x - 1) + 9 (3y - 1) = 25

Solve for x and y, by reducing the following equations in a pair of linear equations : 2x + 3y = 5xy and 3x - 2y = xy.
