Answer:
30 + s = 2s - 10
Step-by-step explanation:
Have a good day!
This is the answer because a number more means +
and decreased means -
times is when a number is next to another number <em>Example: </em>{1(2) = 2}/ 1 x 2 = 2
1- 8.10 . i multiplied , then two negatives do a positive so that’s how i got that
2- -87
3- 2
4=9
Answer:
Step-by-step explanation:
z = 3
2y + z = 1
2y + 3 = 1 {substituting z =3}
2y = 1 -3
2y = -2
y = - 2/2
y = -1
2x +3y +2z = 13
2x + 3 * (-1) + 2*3 = 13 { {substituting z =3} and y = -1}
2x -3 + 6 =13
2x + 3 = 13
2x = 13 - 3
2x= 10
x = 10/2
x = 5
