Step-by-step explanation: Please mark me brainliest!! Im trying to reach a goal and I only need 2 more!! If not its oki.. Have a great day!!
Step-by-step explanation:
if one were to put the y value the equation they could find out what x is for a certain value of y
putting the value of y(1), we get the equation
1=4x-1
2=4x
x=0.5
the value of x when y is 1 is =0.5
NOTE: I got this explanation on brainy on someone else I am not taking the credit
So, there are 3 Apples. Oranges = 2 * 3 Apples = 6 Oranges.
The sum of the number of Oranges and Apples represent half of the Cherries.
Mathematically speaking, o + a = 1/2 c <=> 3 + 6 = 1/2c. => c=18.
So there are 18 Cherries.
Answer: 1/2
Step-by-step explanation:
30x + 18 = 35-4x
collecting like terms
30x + 4x = 35-18
34x = 17
divide both sides by 34
34x/34 = 17/34
x = 1/2
Answer:
I. x = -1
II. y = 1
Step-by-step explanation:
Given the following algebraic expressions;
9x + 10y = 1 .......equation 1
9x - 6y = -15 ......equation 2
To solve using the elimination method, we would subtract eqn 1 from eqn 2.
(9x - 9x) + (-6y - 10y) = (-15 - 1)
0x - 16y = -16
-16y = -16
16y = 16
y = 16/16
y = 1
Next, we would find the value of x;
From eqn 1;
9x + 10y = 1
Substituting the value of y, we have;
9x + 10(1) = 1
9x + 10 = 1
9x = 1 - 10
9x = -9
x = -9/9
x = -1
