" 8."6(ax+by)=3a+2b;6(bx-ay)=3b-2a

Solve the following equations by Elimination method : 6(ax+by)=3a+2b 6(bx-ay)=3b-2a .

Solve the following system of equations by method of cross-multiplication: 6(ax+by)=3a+2b,quad 6(bx-ay)=3b-2a

ax+by=a-b;bx-ay=a+b

(ax+by)^(2)+(bx-ay)^(2)

ax+by=2; bx+ay=3

ax+by=a+b bx+ay=b^2

ax+by=5 bx+ay=3

2 (ax+by)^(2)-(bx+ay)^(2)

Solve: ax + by = a - b bx - ay = a + b

2(ax-by)+(a+4b)=0,2(bx+ay)+(b-4a)=0
