This image contains a set of simultaneous linear equations. Each pair of equations can be solved using methods such as substitution or elimination. I'll walk through each pair and solve them for you.

Let's go step by step:

(1)

$3a + 5b = 26 \quad \text{and} \quad a + 5b = 22$ We can use substitution or elimination to solve for $a$ and $b$.

(2)

$x + 7y = 10 \quad \text{and} \quad 3x - 2y = 7$

(3)

$2x - 3y = 9 \quad \text{and} \quad 2x + y = 13$

(4)

$5m - 3n = 19 \quad \text{and} \quad m - 6n = -7$

(5)

$5x + 2y = -3 \quad \text{and} \quad x + 5y = 4$

(6)

$\frac{1}{3}x + y = \frac{10}{3} \quad \text{and} \quad 2x + \frac{1}{4}y = \frac{11}{4}$

(7)

$99x + 101y = 499 \quad \text{and} \quad 101x + 99y = 501$

(8)

$49x - 57y = 172 \quad \text{and} \quad 57x - 49y = 252$
