`2x+3y=7` , `(a+b)x+y(2a-b)=3(a+b+1)` find the value of `a+b`

if a/3 =b/7 =(7a-2b)/x , then find the value of x.

2x + 3y =7 , (a + b ) x + ( 2a - b ) y = 21 .

2x + 3y = 7& (a-b)x+ (a + b) y = 3a + b-2

If the HCF of 8x^(3)y^(a) and 12x^(b)y^(2) is 4x^(a)y^(b) find the maximum value of a+b

for what values of a and b,the equations 5x+8y=7 and (a+b)x+(a-b)y=(2a+b+1) have infinite number of solutions

If the polynomial 7x^(3)+ax+b is divisible by x^(2)-x+1 , find the value of 2a+b.

If the polynomial 7x^(3)+ax+b is divisible by x^(2)-x+1 , find the value of 2a+b.

If the polynomial 7x^(3)+ax+b is divisible by x^(2)-x+1 , find the value of 2a+b.
