Answer:
x = 42
Step-by-step explanation:
2/7x = 12
Divide 2/7 from both sides
x = 12 / (2/7) = 12 * 7/2 = 42
Answer: x^2+4
Step-by-step explanation:
From equation 1 e=23-6f
sub 1 into 2. 2(23-6f)-f=7
46-12f-f=7
46-7-12f-f=0
39-11f=0
39=11f
then u divide both side by 11
therefore f=3.55
subtitude f in 1
6(3.55)+e=23
21.3+e=23
e=23-21.3
e=1.7
