Question

find the value of m from the equation 2x +3y=m if its one solution is x=2 and y= -2 _____

a) 2
b)-2
c)10
d)0 ​

Answer 1

Answer:

b(-2)

Step-by-step explanation:

2(2)+3(-2)=m

4-6=m

-2=m

Answer 2

[(b) -2]

Steps :

The given equation is 2x + 3y = m . We have been asked to find the value of m which is the final answer of this problem .

We need to follow some simple steps :

1. Find the values of x and y
2. If the values are already given jump to 3rd step .
3. Substitute the values of x and y
4. Do the necessary operations and get the answer !

Following the steps :

➜ 2x + 3y = m

Values of x and y are given as :

• x = 2
• y = -2

➜ 2(2) + 3(-2) = m

➜ 4 + (-6) = m

➜ 4 - 6 = m

➜ -2 = m

➜ m = -2
