She put the y in the same equation ....it was the mistake
She had to put the y in the other equation:
2x+ 22 - 10x = - 2
-8x + 22 = - 2
-8x= -2 - 22
-8x= - 24
x= 3

Find to numbers, A & B,whose Products, A x B, is less than the sum, A + B. Can you find to positive numbers?

NeTakaya

Answer:

any number, n, multiplied by 1 is less than n + 1, so A = 1, B = any number

For example, 1 % 7. 1 * 7 = 7. 1 + 7 = 8

Also, having one of the variables be a decimal can make the numbers smaller.

For example, 28 * 0.5 = 14. 28 + 0.5 = 28.5
