Answer:
The solution is (4, 0)
Step-by-step explanation:
Using Linear combination method to solve:
Since "e" have the same coefficient in both equation with opposite operator; we will add.
Divide both side by coefficient of d which is 3
Since d = 4; put 'd' into any of the equation to get 'e'
Therefore, the solution is (4, 0)
Answer:
a. 24 ÷ 3 = 8 ⇒ i. 8 × 3 ÷ (6 − 3) = 8
b. 53 × 7 = 371 ⇒ h. (8 × 7 − 3) × 7 = 371
g. 8 × (5 × 12 − 10) = 400 ⇒ f. 8 × 50 = 400
Step-by-step explanation:
Given:
We have to match the equivalent expressions:
a. 24 ÷ 3 f. 8 × 50
b. 53 × 7 g. 8 × (5 × 12 − 10)
c. 56 − 21 h. (8 × 7 − 3) × 7
d. 4 − 3 i. 8 × 3 ÷ (6 − 3)
e. 40 × 2
Solution:
a. 24 ÷ 3 = 8
b. 53 × 7 = 371
c. 56 − 21 = 35
d. 4 − 3 = 1
e. 40 × 2 =80
f. 8 × 50 = 400
g. 8 × (5 × 12 − 10) <em>Using PEMDAS rule.</em>

Answers:
a. 24 ÷ 3 = 8 ⇒ i. 8 × 3 ÷ (6 − 3) = 8
b. 53 × 7 = 371 ⇒ h. (8 × 7 − 3) × 7 = 371
g. 8 × (5 × 12 − 10) = 400 ⇒ f. 8 × 50 = 400
c,d and e didn't have any match
a is equivalent to i,b equivalent to h and g is equivalent to f.
