1. The variable A added to the sum of the variable D and 6
2. 10 added to b multiplied by 2
X+4+5x=6x+4
6x+4=34
6x=30 (minus 4 on both sides)
30÷6=5
hence: x=5
Solve this you will get the answer, I am a bit confused in the value of n
= 4* (5730)^n * 17190 / 5730
Step-by-step explanation:
(-23) x 93 = - 2139
(- 16 ) x (- 30) = 480
14 x (- 12) = - 168
Solve the following system of equations:
2x + 3y = 40
-2x + 2y = 20
We can add these equations to get a new equation. Then we can solve for y:
0 + 5y = 60
5y = 60
y = 12
2x + 3y = 40, plug in y = 12 and solve for x:
2x + 36 = 40
2x = 4
x = 2
Choice A
