Answer:
see below
Step-by-step explanation:
The second equation tells us x = y - 3 so when we plug in y - 3 for x in the first equation we get 4(y - 3) + 3y = -5 → 4y - 12 + 3y = -5 → 7y = 7 → y = 1. Plugging this value into the second equation we get x = y - 3 = 1 - 3 = -2.
Answer:
16
Step-by-step explanation:
8/2(2+2)
- According to the rules of BEDMAS, solve the values inside the bracket.
8/2 (4)
- Simplify the fraction outside the bracket.
4(4)
- Multiply the two values.
= 16
7^2 .3(5.2-2.8)
=7^2 . 3(10-16)
=7^2 . 3.-6
=7^2 -18
=49-18
=31
