Question
Complete the following activity, and find the value of x:
5x + 3y = 9 ................ (I)
2x – 3y = 12 ............... (II)
Add equations (I) and (II)
5x + 3y = 9
+ 2x – 3y = 12
7x = `square`
x = `square/square`
x = `square`
Fill in the Blanks
Sum
Solution
5x + 3y = 9 ................ (I)
2x – 3y = 12 ............... (II)
Add equations (I) and (II)
5x + 3y = 9
+ 2x – 3y = 12
7x = `bb(21)`
x = `bb(21)/bb(7)`
x = `bb(3)`
