Question

Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.

(a) 5m = 60 (10, 5, 12, 15)

(b) n + 12 = 20 (12, 8, 20, 0)

(c) p − 5 = 5 (0, 10, 5 − 5)

(d) (7, 2, 10, 14)

(e) r − 4 = 0 (4, − 4, 8, 0)

(f) x + 4 = 2 (− 2, 0, 2, 4)

Answer 1

this is your answer hope this will help you

Answer 2

Answer:

(a) 12 (b) 8 (c) 10 (d) question missing (e) 4 (f) -2

Step-by-step explanation:

Solve the given linear equations for the variable and obtain the answer.

(a) Dividing both sides by 5, we obtain

$5m = 60\\\frac{5m}{5} = \frac{60}{5} \\m = 12$

(b) Subtracting 12 from both sides as

$n + 12 = 20\\n + 12 - 12 = 20 - 12\\n = 8$

(c) Adding 5 to both sides as

$p - 5 = 5\\p - 5 + 5 = 5 + 5\\p = 10$

(d) question missing

(e) Adding 4 to both sides, we get

$r - 4 = 0\\r - 4 + 4 = 0 + 4\\r = 4$

(f) subtracting4 from both sides

$x + 4 = 2\\x + 4 - 4 = 2 - 4\\x = -2$
