Solving the simultaneous equation show that the solution is inconsistent.
<h3>What is Inconsistent solution?</h3>
A simultaneous equation is said to have inconsistent solution when there is no value as the solution. This implies that no value of unknown will satisfy the equation.
Hence no value of x and y satisfies the equation.
4x -2y = 18 ______1
-4x + 2y = -18 ____2
from (1) make y the subject of formular
4x -2y = 18
2y = 4x - 18
y = 2x - 9 ______3
substitute y = 2x - 9 into 2
-4x + 2y = -18
-4x + 2 (2x - 9 ) = -18
-4x + 4x - 18 = -18
-4x + 4x = -18 + 18
0 = 0
This gives no solution hence the simultaneous equation is said to be inconsistent

$69 a day for 5 days that means 69 x 5 then that’s $345 hope this helps
You have to add all of them together for money
Answer:
Terms are 2 , 3 , 7 , 31
Step-by-step explanation:
1) given a1 = 2
an+2 = 2(an) -1
put n = 1
a1 + 2 = 2a1 -1
put value of a1 in above
you'll get a3 = 2² -1
a3 = 4-1
a3 = 3
put n = 3
a3 + 2 = 2a3 -1
a5 = 2³-1
a5 = 8-1
a5 = 7
put n = 5
a5 + 2 = 2a5 -1
a7 = 2⁵ -1
a7 = 32 -1
a7 = 31
Hope you got it.
Similarly you can find 2nd one's term t23
tn = 5*n -4
here n = 23
t23 = 5 * 23 - 4
t23 = 115 -4
t23 = 111
Hope this helps you.
Answer:2x+7=9
Step-by-step explanation:
When it says seven more you add that to the end of the equation and set it equal to 9 then product of a number (x) and 2 so it would be 2x. Hope this helps!
