Answer:
Step-by-step explanation:
<u>Required equation</u>
<u>Solving for x</u>
- 12x - 8x = 10 + 18
- 4x = 28
- x = 28/4
- x = 7
Answer:
x=4 and y=1
Step-by-step explanation:
Equation 1) 3x+8y=20
Equation 2) 5x+3y=23
Equation 1) 5(3x+8y=20 )
Equation 2) 3(5x+3y=23)
15x+40y=100
15x+9y=69
(Take away 40y from 9y and 100 from 69)
31y = 31
y=1
Substitute y=1 into equation 1)
3x+8=20
(Take away 8 from both sides)
3x=12
(Divide by 3)
x=4
7,613 ,7,361,7,136
