Answer:
3+6×(5+4÷2)-7
Step-by-step explanation:
To solve the expression use order of operations.
Right now the expression solves to:
3+6×5+4÷2-7 6* 5 = 30
3 + 30 + 4÷2-7 4 ÷ 2 = 2
3 + 30 + 2 - 7 Add and subtract left to right.
33 + 2 - 7
35 - 7
28
To make it solve to 38, add parenthesis:
3+6×(5+4÷2)-7 (5+4÷2) = 7
3+6×(7)-7 6*7 = 42
3 + 42 - 7 Add and subtract from left to right
45 - 7
38
Answer:x=-2 y=-6
Step-by-step explanation:
11x+4y=-46..........(1)
7x-4y=10..............(11)
Add (1) and (11)
11x+7x+4y-4y=-46+10
18x=-36
Divide both sides by 18
18x/18=-36/18
x=-2
substitute x=-2 in (11)
7x-4y=10
7(-2)-4y=10
-14-4y=10
Collect like terms
4y=-14-10
4y=-24
Divide both sides by 4
4y/4=-24/4
y=-6
