Question

2. Solve the following simultaneous equations,
(1) 3a + 3b = 26; a + 3b = 22
a . (2) + 7 = 10: 3x - 2y = 7
(3) 2x - 3y = 9; 2x + y = 13 (4) sm - 3n = 19; m-on-7
10
11
* (5) 5x + 2y = -3; + 5y = 4
32x+
(7) 99x + 1019 = 499; 101x + 997 = 501
(8) 49x - 57y = 172; 57x - 49 = 252
Let's recall​

Answer 1

Step-by-step explanation:

1)3a+5b=26- - -eqn 1

a+5b=22- - - eqn2

From eqn 2

a+5b=22

a=22-5b

Put a=22-5b in eqn1

3(22-5b)+5b=26

66-15b+5b=26

66-10b=26

-10b=26-66

-10b=-40

10b=40

b=40

Put b=40in eqn 2
