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
Answer:
x=96
Step-by-step explanation:
3/8x=36
Multiply both sides by 8/3.
x =96
I don’t really know but here’s an example of another one maybe it’ll help
Use PEMDAS :
Parenthesis, Exponents, Multiplication & Division, Addition & Subtraction
[3² + (7 · 6 - 2²)] - [30 ÷ (4 + 1)]
[3² + (42 - 4)] - [30 ÷ (5)]
[3² + (38)] - [30 ÷ 5]
[9 + 38] - [6]
[47] - [6]
