Multiply first equation with 2. Then add first and second, we get -x=6. X=-6 and y=-29
H=-16x to the second power +136
If im correct it would be -2(2)+4(-2)-5 which is -4-8-5 which would be -17
Answer: M = 2
Step-by-step explanation:
Given equation: m+3=5
You need to isolate m so you can find its value. Subtract 3 from the left side, and do the same to the right side. Subtracting 3 from 5 as well makes the number become 2 on the right side of the equation. Therefore, m=2.
A rule you should always remember is when you have a value on each side of the equal sign, whatever form of addition, subtraction, multiplication, or division should be done to the other side as well.
