Gennadij [26K]

Multiplication is helps to add a number multiple times. The meaning of  6 x 5 is 6 + 6 + 6 + 6 + 6.

5 x 6 = 5 + 5 + 5 + 5 + 5 + 5 = 6 + 6 + 6 + 6 + 6

Hence, the meaning of  6 x 5 is 6 + 6 + 6 + 6 + 6.

2x – 3y = -5
vampirchik [111]

Answer:

y = 3

Step-by-step explanation:

2x-3y = -5 --------- (1)

y = 2+x ------- (2)

substitute (2) into (1)

2x-3y = -5

2x-3( 2+x ) = -5

2x-6-x = -5

2x-x = -5+6

x = 1

substitute x = 1 into (2)

y = 2+x

y = 2+1

y = 3
