Question

1. $-6 = \frac{3}{5}y$ 11. $-6 =$ 13. $c - 5.3 = -6.4$ 14. $-\frac{1}{3}$

Explanation:

Step1: Solve for $y$ (Q10)

Multiply both sides by $\frac{5}{3}$:
$$y = -6 \times \frac{5}{3}$$

Step2: Calculate $y$ value

Simplify the expression:
$$y = -10$$

Step3: Solve for $a$ (Q13)

Add 5.3 to both sides:
$$a = -6.4 + 5.3$$

Step4: Calculate $a$ value

Simplify the expression:
$$a = -1.1$$

Answer:

For question 10: $y = -10$
For question 13: $a = -1.1$
