The given equations are:
5x - 2y = 88
3x + 4y = 58
Multiplying the 1st equation by 2, we get the new set of equations as:
10x - 4y = 176
3x + 4y = 58
Adding the two equations, we get:
10x - 4y + 3x + 4y = 176 + 58
13x =234
x = 18
Using the value of x in 1st equation, we get:
5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1
So, the solution of the equation is (18, 1)
Answer:
The third one is 92
Step-by-step explanation:
Because of the order of operations you do 8x3 first. 8x3= 24. So now our equation would look like this... 80+24÷2. Now 24÷2=12. so now our equation looks like this... 80+12=?
80+12=92
Answer:
<h3>(1,1) and (2.5)=3.6</h3>
Step-by-step explanation:
i think it is 3.6
Answer:
$336
Step-by-step explanation:
